Took car in for repairs was charged over $2300, 2mos later and less than 500 miles it broke down WITH THE SAME ISSUE! Big Nick's towed it and said all was under warranty. After 2 weeks and very poor communication I got it back again but this time it was leaking when it wasn't before, took it back AGAIN only to be told the original problem really couldn't be fixed due to them not being able to test pressure?! They should have known all of this at the onset, there's good reason shops are AAA certified, do research, this shop would NEVER qualify! read more

I have done business with Big Nick's several times. I feel Nick is over booked with appts he forgets when he tells his customers to come in. I went there twice, and neither time did I receive good service because he forgot. He promises his customers that he will throw something in for giving him business then doesn't do it. His wife works in the front to make the appts she's a trip VERY RUDE to customers. He needs to hire someone that is professional because she will leave a nasty taste in your mouth. I will never give them another cent. read more

Nick and Jamie have been so great to us! Ever since 5 years ago when I needed a clutch replacement and they were the best priced, we haven't gone anywhere else. Honest, friendly service, and close to home :) read more

I needed an alignment on my truck the other day so I called up Big Nicks. He fit me in about 2pm that same day. I brought my truck in and waited in their lounge for it to be completed. They seemed pretty busy but were able to get things wrapped up in about a 1/2 hour. I really appreciate the quick turnaround time. You guys are awesome. Thanks for the great service and have an awesome holidays!! read more

Let's start out by saying they were very nice in the beginning. I I was late for the appointment and they still let me drop off my truck. They were supposed to call me that night and let me know what the issue was. I received a call two days later which isn't a big deal. they told me what the issue was, and that they were going to further look into the matter for me because I wasn't understanding why that happened and was wondering if there was another underlying cause. They told me the total price of the vehicle repairs this place does not have any type of financing, which again is a big deal, but due to the price of the repair, I knew I would need to come up with money. unfortunately due to the times of the shop open at eight and closing at 5:30. It would be extremely hard for me to pick up my truck after they ran the diagnostics. As I get off of work at five and I work in Westminster. Goes by, they call me understandably a little aggravated that I have not yet picked up the truck. They let me know that they will leave the key somewhere for me outside so I can pick it up when I get off of work. I was told I was going to receive a photo with the whereabouts of the key. This did not happen so on Thursday morning the night after I was supposed to receive a text message I decided to go to work late go to the shop pull some tools from my work truck get the key so that later that night I could come and pick up the truck. whilst arriving before 8 AM, the mechanic came out and proceeded to scream at me for not moving the truck. I let him know that I was told I was gonna receive a text message the night before of where my key was going to be he proceeded to yell at me and tell me we sent you picture she sent you a picture and I sent you a picture is what he told, I showed him my phone and told him I did not receive any pictures but I'm here to get the key right now and I can move the vehicle if it is hindering. He proceeded to yell at me about the issue about how I'm blocking all of the cops she came out and started to scream at me as well saying I sent you a picture and then I continue to tell both of them I did not receive a picture I can move the vehicle right now, then she says well I forgot to send you the picture, but I told you where the key would be. I said well I was waiting for the picture to show me where it was at and that didn't happen. He then takes the key from my hand and says well we're gonna need to hold onto this key until you come pick up your truck I said give me my key right now and I will move the vehicle off of your site right now. I continue to try to talk to him calmly, even after he stepped with an inches of my face, and proceeded to yell at me telling me I needed to listen to him. After this aggressive exchange, I decided I would not want to do business with them, and requested my key so I could move the vehicle. I have since moved the vehicle off of the lot and will not be returning. Again, they were really nice in the beginning they did not charge me for the diagnostics. but unless you feel like you want to have a screaming match with two employees of this auto shop, I suggest you do not do business with them. I will be awaiting communication from somebody on this yelp review as I believe their argumentative attitudes will not allow them to see this, and not have some sort of rebuttal. This is why people do not tend to do business with smaller shops, or family own businesses because of the way the employees act. I am very disappointed with the way I was approached this morning. Hello again! I believe I got upset after you and your husband tried to have a screaming match with me out front. If you both would learn to keep your mouth closed and listen to a customer we would have had an understanding. Don't forget you admitted to not sending me a text message with a picture and information on where my key would be. Ridiculous how after admitted that you returned inside. I arrived at 7:55 to get necessary tools for my work day as well as get my key to move it off the lot, as well as let you know I had the money to make the repairs and schedule a date to return with my vehicle. But, instead of giving your customer a chance to speak the owner chose to come out of the building screaming at me. Through this entire "conversation" I kept asking him to calm down and let me speak. Which he many times told me" I will speak and you listen!" Not the best way to handle a business!! Thankfully i decided to take my truck and business elsewhere. As my truck is fully repaired and for a lot less money than what you were charging and I did not have to deal with two very unprofessional business owners. I thank you for your award winning attitudes. As it saved me a ton of money! I've very every bad review on your business, it's insane how many people talk about both of your attitudes and how much you over charge your customers!!I hope you guys enjoy your weekend. read more

Played games with insurance trying to get more money, which resulted in major delays. Seemed loose with the truth regarding the estimate process and our adjuster was very frustrated with the inconsistent supplementals and weird repair recommendations. Won't be going back. read more

So happy to have found a competent, friendly, and honest auto shop in my new home. I had no idea what was wrong with my car and was ready to buy a new used car, but Nick did a thorough assessment, gave me options, a price estimate and we made a plan. His team, including his wife, got everything set up and provided the repairs in a timely and efficient manner and all is well. I highly recommend Big Nick's Automotive and Diesel Repair Shop. read more

I felt as though I WON the LOTTERY!!!!!!! On Tuesday, my car was making concerning sounds so I called Big Nick's Auto to see if I could bring my Audi in, & Jami said sure even though they were really busy. When I got there, Nick took a quick look at my car and said it wasn't great news which I expected. It was going to cost between $500-$1,000 depending if the wheel bearing could be saved. I could not afford to have my car fixed, & I knew how long it would take me to get to work taking buses and trains so I was in tears leaving my car there hoping my husband would help me. Unfortunately, he did not want to put any more money into an older vehicle again. When I went back to Big Nick's Auto to pick up my car, Jami, Nick, & their Boxer Chaos were standing there. As I was still crying, I said I'm here to pick up my car, & they said no you're not, we are fixing your car for FREE!!!!!!! I started crying harder in disbelief, but Jami said they choose someone every Holiday Season to HELP, and they CHOSE me!!!!!!! My car was ready the same day. I CANNOT THANK Big Nick's Auto enough for their HUGE generosity. I REALLY do feel as though I WON the Lottery!!!!!!! read more

This place is great, the staff is very nice and honest about what could be done versus what needs to be done. Highly recommend! read more

Yesterday, I dropped my Fiat 500X off at Big Nick's to diagnose a rattling noise under the front of the vehicle every time it hit a bump in the road. I expected to pay thousands for this repair. Instead, I walked out with new sway bar links and a bill of $266.85. I couldn't believe it. Such a low price and a great value. The price was more than fair and there was no evidence that the price for parts had been unfairly marked up or the labor rates unreasonable. I will be back again. This is a great group of people with fair and honest pricing. That is exactly what I need from an auto shop. And, get this. I was so impressed that I wanted to tip them $200, but they said they could not accept tips. They simply requested that I refer new customers to them. Fair enough. That's what I am doing. Great people! Big Nick's is awesome! ~Stan Monroe read more

Brought our car in for AC repairs and told them that we did not need the system to be charged but that the condenser fan needed to be replaced. They said they charged it anyway at a cost of more than $300.00, something I could have done at home in 10 minutes with a $40.00 AC charger from AutoZone. They they charged another $700 to replace the condenser fan. We feel ripped off and will never take a car there again. read more

Had repairs done on multiple occasions and am very pleased! Quality of work and fair price! Will go back!

I called Big Nick's Auto to see if they could fit me in to take a look at my wheels after I hit a curb. They were able to fit me in 2 hrs later. I got there for my appointment and they looked at my car asap and done in about 15 minutes. Not only were they fast but also told me I didn't damaged anything and just needed a wheel alignment. I was thinking it was going to be costly for a wheel/axle repair, which they could have easily said. No charge for looking at my car. I asked if they could do the alignment but they said they don't offer that service and pointed me to the tire place next door. If you want a quick and honest auto repair shop, this is the place. read more

I ran out of gas right by their shop. Everyone was so helpful helping me out and getting my car started again. Thankful for good people. True test of character. read more

Big Nicks is the spot, and they reflect discipline and integrity. Anything from simple tune ups to full on transmission builds, they have you covered. The shop is as clean as the work they do! Thank you for taking care of my German engineering lien it was your own. read more

I can't say enough great things about Nick's. They are friendly, responsive and reasonably priced. Most of all they truly care about the customers. I have never been to a business that shows such genuine consideration. Plus Nick can diagnose and fix just about anything - he's like a "car whisperer"! I simply won't go anywhere else with my vehicle needs and repairs. Big Nick's is the best. Period. read more

Big Nick And Crew Are Outstanding. Please Do Not Pass By. Staff Goes Above And Beyond To Keep Customers Satisfied. Strongly Recommend. read more

I'm just blown away by the incredible customer service and ethics of Nick and team. My check engine light went on 3 days ago on my 2016 Ford Edge and the Ford dealership wouldn't even schedule an appointment for me. I was of course terrified of an impending break down, being just shy of 50k miles and in desperate need of a vehicle as I'm starting to commute back to the office again. I brought my car in yesterday to Big Nick's and they got to it today already. Immediately gave me a call and didn't even charge for the fix because the only problem they could see was a faulty O-ring. I mean, when does that ever happen? I have found my service and maintenance provider with Big Nick's for as long as I live in the Denver area! And I will certainly refer anyone else I know to them. Professional, courteous, honest, knowledgeable and expedient. I've already scheduled my next oil change with them. Thanks Nick, Jamie and team! read more

I go here regularly to get oil changes and always appreciate how they fit me into their schedule. They have a sweet shop dog and I trust the mechanics. Love supporting a small local business with kind and honest employees. read more

So, once again, the plastic "thingy" under my vehicle came off. This time my fault..(don't ask). On a Wednesday I called Big Nick's and was told to come in on Thursday. I arrived at 1:45 and was out the door 15 minutes later. At no charge. I have driven by this business many times, over the last few years, I've lived in Aurora. Now, I know why they're always busy. Very professional. You will definitely see me again, for my oil changes, etc! Thank you! read more

Nick helped me figure out a few things on my jeep and had been an amazing help. The whole crew runs like a well oiled machine!

Recently was stranded via my starter. Had done some research on yelp and facebook and chose Nick. So thankful I did as I have had some recent BAD luck in two other locations. Nick took my towed car right in and had an immediate quote for me. My comfort level was stable and had him look into an additional leak problem. His communication was wonderful and his quote came in $200 lower then the last. He was honest and exact on parts and time spend, even came in a little under his quote. I have since ask him to help with a second vehicle, engine, replacement!! I will update once complete! Thx Nick read more

the number you call on google is his personal number which he can call and text you with. he will harass you along with not complete your car. they only look at the most expensive problem it could be and not anything else wrong with the car. they are about quick over quality which seems nice until your car breaks down 2 weeks after you have them see it. read more

Awful costumer service from over the phone, I called to check availability and the woman was very passive and rude honestly wouldn't trust my car with these people read more

I took my truck in to get a new motor replaced. From when I got the truck back it did not run correctly and eventually ended up blowing it. They took off my radiator mounts and never put them back on and never put the motor in correctly either bolts and hardware were missing from my transmission(a part they weren't supposed to work on) in total a $3000 motor job ended up being over $7500 to fix correctly. When asked if there was anything Nick could do he only got angry and started to cuss at us. -missing bolts in transmission -missing bolts in headers making them warp and not fit new motor -brand new radiator that was correctly installed before came back without bolts and missing the mounts causing a hole to form. -put the wrong parts on motor - gave us a bad motor that already had coolant and gas in the oil. I would recommend to never come to this establishment. read more

The staff at Nick's is wonderful. I was here from out of state, babysitting grandkids. My son's car suddenly had oil streaming from underneath. I called Nick's. His wife was very helpful. They actually came and picked up the car, repaired it and returned it to me since I didn't have a way to take it to them with 3 small children. They corrected what Grease Monkey damaged. The cost and service was excellent. Thank you so much. read more

I called Nick this morning to inquire upon an oil change. He said he would get it right in. When I showed up, there was a line of cars and the wife and I prepared for a long wait. Looks were deceiving. The crew had just cleaned the shop and got me in and out with expert efficiency. This is a family owned, LOCAL, shop and they treat you as such. When they say "nice to meet you" as you shake hands you'll find you're reciprocating the feeling. Excellent customer service and a pleasant experience. Their prices are also better than you'll find at all the big name nationwide stores. The shop is not very visible and they do not advertise except word of mouth and, of course, Yelp. Thank you Nick and Jamie. It was very nice to meet you two. read more

These guys deserve a shout out We bought our Toyota Avalon 12 years ago and it has been a super smooth riding vehicle that's been easy on gas. In all this time we have been here and there to get minor maintenance and repairs done, but nowhere that has been worth returning to. When we moved to Centennial/Aurora a few years ago we found Big Nicks. I am SO thankful we did! The owner, Nick, and his amazing partner, Jamie, have been incredible. They have built up our trust by letting us know the essential repairs necessary and when we might hold off on less urgent items. This week we bit the bullet and had several repairs fixed up. Today when I picked up our Avalon, it was liking driving her brand new again. She is driving Amazing like we are in the clouds. Oh and the customer service is incredible kind and welcoming. Ladies, you know what I am talking about when you go into most commercial repair shops or dealerships... I often feel out of place and am treated like another number in the queue waiting to get taken advantage of. But not at Big Nicks. I am always treated like a good friend with jokes and All. Thank you guys for all that you and your crew do to take care of your community and keep our vehicles running safely! read more

I can't say enough wonderful things about Big Nick's Auto. Top notch mechanics ! Very honest and forthcoming about my maintenance on my acura MDX! Top quality work. I'll never go anywhere else! read more

Big nicks auto is a BIG deal! This family run operation went above and beyond to help me with my car problems (which they solved), very reasonable price, any questions I had were met with grace and honesty. They really treated me wonderfully and not once dismissive! Jamie, Nick and crew, thank you so much for the service you provided me, you've gained a customer for life! read more

Went in for a free estimate on my truck and the lady at the front desk who helped me was super nice and professional! I had a mechanic who wanted to buy the truck so I sent a family member to pick up truck and get ready to sell while I was working. Nick got angry and charged me $70 for the estimate. When I contacted him about it he said he would refund the $70 because the website clearly states they give free estimates. Never received the refund. I don't recommend this place to anyone if you are looking for a professional Service. Bad business etiquette. read more

Honesty and fast service is the name of the game at Big Nick's Auto. I had a tire that couldn't be fixed and they adjusted it for free so I'd make it to the store where I bought it! read more

I walked in to get a headlight replaced after not being able to do so myself. The service I received was above and beyond anything I ever expected walking into an auto repair shop. They were very friendly and super quick I was in and out in less than an hour. My total bill came in under what they originally quoted me. I'll definitely be back!! read more

We took our truck to Nicks for a small oil leak. We have a new driveway and did not want it to get spotted with oil. The estimate came to $2,200,for the oil leak and a few other things they said were wrong. They changed the hoses on the power steering. When we brought the truck home the power steering was making an awful noise and the truck was now leaking more oil. We took the truck back, still the problem was not fixed. Now we have coolant leaking into the oil. The funny thing is we haven't even driven the truck 50 miles since we took it to Nicks the first time. For the amount of money we paid $2,200.00, we can't even drive our beautiful truck. Nick told my husband he did not feel comfortable working on our truck any more because we complain to much. Buyer Beware! Response to NIcks Auto, your information is incorrect. We never took our truck to 3 other shops. Yours was the first one, and you came highly recommended. We did take the truck back to you, and you told your coworker to check the coolant and put some in. How did you know there would be a problem with that? Now all of a sudden there is coolant leaking into the oil. We took the truck to one othe place,because you told us to take the truck to another garage (because we were too hard to please) we did,and were told the oil is overfilled and had coolant leaking in the oil. Nobody touched the engine but you.The truck is now undrivable, because we do not want to ruin the engine. To resolve this you could have done the work right in the first place. 1. The power steering. 2. The coolant leaking in the oil. 3. The oil leak. We are not hard to please we simply feel that the job should have been done right in the first place. We feel we were set up for more repairs and charges. You took advantage of a senior citizen. Remember you were paid $2,200. You should do the right thing. read more

Big Nick's Auto is awesome. Brought in my truck because the A/C wasn't working on a Saturday morning. Nick was able to diagnose the issue based on my description of the problem. Quoted me a price, then squeezed me into a busy question. Few hours later got a call that it was done at the price quoted. Ice cold air now. Thanks Nick. read more

I stopped by to see if I could get an oil change to fix an issue I had when changing my own oil at home. They were able to squeeze me in which was great but told them I only needed new oil and the oil pan drain valve looked at, the oil filter was brand new. They completed the oil change but changed my filter anyway, not a fan of people that don't listen. Service staff was friendly and they did find the problem. I would most likely return. read more

Very helpful guys, changed my struts in less than 2 hours. Quick friendly professional service, plus donuts and coffee in the waiting area! Thanks guys read more

I think I've just had the most pleasant experience that I've ever had at an automotive repair shop. This included calling the business for an estimate and scheduling, pricing, fast and honest service. Especially nice was the personal touch offered by Nick and his wife. What more can a consumer ask for? Excellent! read more

This place is a joke! I contacted them to purchase a turbo and paid up front. Due to the fact that I live 4 hours away Nick said he would ship it. After payment and being told it was shipped I never received tracking info. After several attempts to get the tracking info I randomly get a text saying he lost the tracking info and I never received the turbo. A week later received another text saying he received the turbo back and has not responded since. My truck is my work horse and he has put me out of work for weeks. I highly advise to stay away from this place. read more

I've lived in Denver/Aurora for 10 years and have been going to Big Nick's for about 3 of those years. I wish I would have found them sooner. Great customer service and rates always 5% lower than even the cheapest places around that I've found. That doesn't mean it's less service though! We've had 3-5K worth of work done in the past few years and it's been easy and well worth it. They've always gone above and beyond with even the small things that we bring up. Best mechanic I've been to in a long time! read more
