    My car

    This is the only place I go to get my oil changed. I trust these people and always leave with a piece of mind, which is very important to me; there's not a lot of people you can trust with your car. If there's an issue with my car I know they can guide me on what to do with their expertise. They are always professional and nice people. Josh and his team always go out of their way to help. Highly recommend, you won't regret!

    I was sexually assaulted by one of the technicians at 8080 E. Mississippi Ave Denver,CO while getting my oil changed. It happened a couple of months ago, however, I am still traumatized. Stay far away from Grease Monkey #14!!!!

    Like most mom n pop shop, this place is a gem! Super nice and polite family that will work on your car carefully and thoroughly. Another thing I really appreciate about this auto shop is that I will never have to worry about being ripped off from these people. Pricing for conventional oil change is a little bit more than other chain auto joints but I would totally pay more for a peace of mind and effortless experience. Highly recommend! P/s: the main office will be on your right as soon as you turn after the yellow "50c car wash" sign from Parker.

    First I want to say I tried out this grease monkey because they had no wait and they were near the vet I take my dog to. I dropped off my pupper and came in here for a much needed oil change. It took a solid 5 minutes to flag down a staff member because they don't come into the waiting area often. The access is wonky, you can only drive in from EB mississippi, so the approach was awkward. They charged me close to $70 for an oil change. It's a steep price! I've never paid more than $40 at other leading businesses. Grease Monkey neglected to rotate my tires, they neglected tell me my front brakes were almost entirely gone, and didn't bother to notice that I had a leak from under my car. Oh, but I was in and out in under 20 minutes. I would much rather wait the extra 10 minutes and find out if my car needs anymore work. I feel like I got a $25 service for almost triple what I paid. I recommend going elsewhere for quality service. If you want a quick service this is a good place to go, otherwise I recommend taking your hard earned money elsewhere.

They replied that I needed some new engine gaskets. Okay but I didnt need new gaskets! Furthermore there is no way to check if the gaskets were actually replaced. (You cant see them, they are internal). They did in fact replace the battery, but did not discard the old one, as requested. They left it in the bed of the truck. While boasting about being the BEST shop in 2026, they are very sly about padding the bottom line. Do yourself a favor & use the shop across the street. All Pro Auto Repair. (Just behind Jambo Auto Sales) Dave Caple is very honest & only does the work requested. He will at least call first if he finds more work is needed. I took my car to Dave for a tuneup. He called me back an hour later to inform me a tuneup was not necessary, that everything looked good. Hotchkiss on the other hand would charge me for a tune up after having done nothing.

    I really liked him, appreciated his work. I hired him to…read morereplace the power steering pump, the cost was absolutely cheaper than other places especially because I bought the part my own. After the work done, the car felt pretty much same or sometimes even worse, for example the handle gets really stiff to turn. He says that it's very normal process because the air has to be bleed out. Weeks have passed with same issue so he came to check the car again and said there's power steering pump rack problem. The rack is usually $1000-2000. Personally didn't really think it would be the rack problem with several reasons and decided to take the car to bigger auto shop. After diagnosis, I was told that the power steering pump is failed because when it was replaced, the flush should've be done but since he skipped it, now debris in fluid damaged not only the whole new pump but also hose and reservoir. Of course as car owner, I was definitely frustrated with the fact that now I have to pay extra more money than before when I thought I could save money because of how mechanic guy has done. I personally had to pay new power steering pump+labor fee but now I have to pay another new power steering pump+hose+reservoir+another labor fee. I will accept the fact that I was asking money back at first because.... who wouldn't? It might not be making sense to ask money back for damaging the new power steering pump by how poorly worked done but I thought the labor fee at least would've been made sense. Instead of taking accountability, he would be defend and saying the book he learned from says that power steering pump replacement is totally okay without the flush and had no problem with all other cars or sending me the google search screenshots. Of course the warranty wouldn't cover anything of things even if he damaged the new part and extra parts of car. Currently I wanted to see more opinions than one or two so took the car to another new auto shop, they also agreed that power steering pump is failed and with high possibility from how it was worked done. Surprisingly the rack itself doesn't look like having a problem, different than what this guy said. People at auto shop also say that flush is very necessary for the pump replacement, especially when the car is old. As I personally said to him, people can always make mistakes but important thing is how to handle. I got an apology eventually. But I wasted money. The other thing, he advised me to replace rear break pads soon. I went to check the break pad recently, all my break pads are not needed to replace due to adequate thickness. I would say he is a capable man to do some works on cars but I can't say he would be with more complicated jobs.

    I want to start off by yes, this was a convenient mobile service at the time when it came to…read morereplacing an A/F sensor, but I'm having issues with that recently due to taking my car to the dealership. They reported that the A/F sensor is faulty/needs replacement. I have since requested a full refund for that service since they installed a faulty A/F sensor and have not received that as per contract.. To say that this mechanic has screwed me over is an understatement. Do NOT waste your time or your money here! Originally I had Sage quote me for a torque converter replacement for $1020.43. I got a phone call later letting me know that I needed a transmission replacement instead. He told me the labor would cost the same since the car was already taken apart and we would discuss where to get the transmission. I was given two options; $1500 used transmission with about 30k in miles or a remanned transmission for $3000 with warranty. I was highly advised to get the remanned transmission because it would have a warranty in case any issues were to arise. And I'm so glad I did because the transmission company from CA refunded me in full after sending me a faulty transmission then the nightmare began. Sage Automotive was extremely unprofessional and bit off more than they could chew. If you look at their available services here on yelp, transmission replacement is not listed. Sage could've easily done the right thing and said, "Hey, you're going to need a new transmission. I don't have the necessary skill set to do that let me refer you to ..." but no, I was reassured about the service and that it would not take more than two weeks. My car was held hostage for almost two months. I was given the run around every time I would ask for an update and treated as if this was a project car when this is my primary source of transportation. The job got pushed back multiple times for different reasons; technicians getting sick, wife's birthday, food poisoning, etc. I would understand if this was a favor that I asked from a friend but I'm literally paying for a service and was neglected as a paying customer. I paid for the transmission along with the labor in FULL before the service was even completed!!! So why prolong the process when you have been paid? I dropped the car off Dec. 26th 2025. Thursday Jan 7th the transmission was delivered and January 12th the transmission job was supposed to be done. I had a trip planned and was hoping I would have my car before January 13th. Come Tuesday Jan. 13th I have my flight out of town and I was given no phone call, text or email update on my car. I had to reach out to Sage myself 2 days after the agreed due date to make sure that I would receive my car when I got back that Saturday. I was told by Sage that my car would be ready by then, but to my surprise I had received a phone call while on vacation only to be let down yet again and that they would need a couple more days. On this phone call I was not given a due date for my vehicle, "... I don't want to put a due date on it because it seems that every time we do it gets pushed back." Also " I spent $400 on tools for this job.." Why is this relevant to me? Normally that wouldn't fly at other shops. Why couldn't Sage do the right thing and be transparent that he COULDN'T HANDLE THE JOB. I was also told that I would be reimbursed for a car rental (no amount or type of car was specified on said phone call). I went through Costco because it was the cheapest option and was billed $196.18. My total was a lot more due to insurance fees but I ate the cost of those. I had no say in the type of car I was given, I rented it for 4 days to get me through the weekend and to my early shifts that week. I only asked Sage to cover the $196.18. After sending Sage the bill I was met with a passive aggressive email written by AI that said they would only cover up to $150 for a 3 day rental and criticized the choice of vehicle because I should've chosen something of "equal value" to my car. Using AI to write a business email seems really counterintuitive to just reaching out and asking more questions about the rental costs instead of making assumptions. They also requested email to be the only form of contact moving forward to save their ass from making more commitments they couldn't follow through with. I paid $1251.05 for the job and was told that the new transmission was faulty. Sage reached out to the company in CA and they were able to send a new part replacement and cover the labor cost for the part replacement. Outstanding service from those guys. The part arrived Monday Feb. 2nd and I reached out that I would need my car no later than Tuesday Feb. 3rd. Let me preface that the valve body part replacement is a simple quick job for someone that knows what they're doing (2hrs).

    NEVER. GO. HERE These guys are thieves and goons…read more Literally go anywhere else. I have never felt compelled to write a review for a business until the HORRIBLE experience I have had at Mud's Tires. They've got GOONS working there and this shop should be avoided at all costs. Earlier this year, I brought my Jeep into Mud's to see what it would take to get my check engine light turned off. Well, 14k later, my check engine light is still on. This is the most back-alley and illegitimate mechanic shop I have ever dealt with and I am embarrassed I ever went here. After having to bring my Jeep back into this shop and having it stay over night there for a total of 60 days this year, I decided to cut my losses and accept that these dirtbags were never actually going to honor their "warranty." Mud's claims to have a warranty for all work performed but they won't actually honor that, when you inevitably have to bring your car back in when their shotty mechanic work immediately fails. They will try and convince you that you have to spend more money with them to actually fix the problem this time. They will pretend to work on your car while they keep it for a few days/weeks and you are without a way of getting around. This happened to me and when I complained to the owner he tried to gaslight me and tell me the issues I was having with my Jeep, after paying him thousands, were somehow my fault? I've attached a screenshot of the convo to this review, in which the owner of the shop tells me "I'm not your daddy," after I complained to him about the mechanical work the goons he's got working in there did on my Jeep. Also, I recommend scrolling down a few reviews to read about one customers experience at Mud's in which she over hears the owner complaining about "blacks." This is the kind of shop Mud's is. NEVER GO HERE. They will rob you and your car will run worse than it did before you brought it in. The owner will act like he's your friend and that he's giving you a deal. Run. He's a hustler and don't fall for his tricks. He is not your friend and he will rob you blind if you give him the chance. Lastly, I asked the owner for a 6k refund after his goons essentially totaled my Jeep and he said he would sue me for defamation if I gave him a bad review. I've attached a screenshot of that interaction with him as well. Apparently customers take him to court often? Go to a real shop that can actually honor their warranty and has actual licensed mechanics.

    Yelp Review - Sal's Auto Tech, Centennial, CO I've never had…read morea more traumatic automotive experience in my life. On March 4, 2026, I drove my 2007 RAV4 to Sal's Auto Tech for a simple battery and alternator replacement. My car is my lifeline and income source, and at the time, my temporary home. I called the shop that morning; Audrey was friendly but told me I'd need to bring the car in for an estimate. I arrived around 10 AM, waited an hour in the office, then the mechanic took me to the shop -- my car was already lifted on the hoist. Instead of focusing on my simple request, the mechanic spent hours inspecting tires, brakes, suspension, and the underside, ignoring me repeatedly. I eventually asked about the price for the battery and alternator. The mechanic acted offended, and another employee quoted $1,700. and they installed them, but during the process broke my radiator. Then I was told a piece of my radiator had been broken by their mechanic. They said it could be fixed the next morning. I asked if I could stay in the parking lot safely overnight -- they refused. When I requested my property back, they called the police and had me trespassed. I was humiliated, scared, and forced to drive 7 miles to a Walmart parking lot to sleep safely. The next morning, I towed my car back to the shop ($190). I met with Sal, gave him the broken radiator piece, and he was rude, dismissive, and baffled that their mechanics had broken it. He told me I was trespassed and could not stay near the property. Even after two days, the radiator was still not properly repaired -- just topped off. On March 6, they sent me a handwritten note falsely blaming me for radiator damage. The accusations were completely false and misleading, adding stress on top of an already humiliating situation. I drove 10 miles to Denver, and the temperature gauge went immediately red. I went straight to Jiffy Lube, where within five minutes, they discovered the lower radiator hose had never been connected, spilling coolant everywhere. They fixed it promptly, refilled the radiator, and confirmed my car was safe. During this entire ordeal, I lost income every day, was ignored, dismissed, and gaslit, and experienced fear and humiliation from being trespassed and blamed. The shop clearly took their time because they knew I couldn't confront them on-site, and their attitude made it clear they found my distress amusing. My experience was not just bad service -- it was emotionally traumafinancially damaging, and completely unprofessional. If you rely on your car for work, safety, or even basic transportation, do not go to Sal's Auto Tech. They broke my property, refused to take responsibility, involved the police unnecessarily, and left me stranded. I cannot overstate the stress, fear, and frustration I endured. Honest, competent mechanics at Jiffy Lube resolved the issue in minutes -- something Sal's could have done immediately. Avoid this shop entirely.
