Everyone seems to have a complaint or a bad story about an experience with an auto mechanic or repair shop, seldom do people talk about the good experiences they do have. I am happy to talk about the experience my family has had with Gregg's. My wife took her car in for an oil change using a Groupon. Upon completing the oil change, Gregg's guys performed an inspection finding various issues that needed to be addressed providing my wife with a very reasonable printed estimate. You would figure this is when the pressure to get the services completed would start, but it didn't. They said thank you for your business and sent her on her way. Fast forward a couple of weeks, my wife called and made an appointment for the repairs. They got her car in quickly and made the repairs without haggling or trying to upsell additional or unnecessary services. Gregg and his guys were professional, honest, and quick. We will be back and will recommend Gregg's Mobil to anyone in need of a recommendation for an auto mechanic. Also, as a former Marine, I appreciate the Marine Corps flag being flown out front! read more

We took our car to Gregg's Mobil in Mission Viejo on July 18 for a routine oil change. We drove in with a perfectly working vehicle, picked it up an hour later, and immediately noticed a strong oil smell. Minutes after leaving, the car became undriveable and stalled -- steering failed, oil was pouring out, and the drive belt was damaged. Tried calling Gregg's repeatedly -- no answer. Employees had left early, even though the shop was still "open" according to their posted hours. No after-hours contact, no help. We had to scramble to find another mechanic and a tow truck. Turns out, the work Gregg's did led to nearly $600 worth of damage: leaking oil all over the engine and breaking the drive belt. We paid out of pocket to fix these issues. When we went back Monday, Jeff the manager was rude, dismissive, and blamed us for not towing our car back to them (which we tried to do). After pressure, they agreed to reimburse the cost of repairs (the least they could do because they were at fault for them) -- but refused to refund the oil change that caused the damage in the first place. So basically, I had the privilege of paying $200 for an oil change that caused $600 worth of damage. Both Gregg and Jeff admitted fault, but still refused full accountability. The experience was frustrating, stressful, and could've been dangerous. Thankfully we live nearby, but if our car had stalled in an intersection or the freeway, this could have been catastrophic. Worst of all, Jeff and Gregg were condescending and extremely apathetic to the situation. Avoid this place unless you want poor workmanship and worse customer service. read more

saw the man that does the smog check being extremely rude to women on more than one occasion. And smog check prices with "an alleged coupon" that he's giving you is still outrageous. Lots of other places for smog checks with better prices and better customer service read more

I needed the air on tires checked and, although it was closing time, the gentleman took care of my tires anyway. Josh was friendly, efficient and careful. Thank you very much read more

This was my 2nd time visiting. I decided to get my suspension Strut and Coil Spring assembly replaced. I received all details of work performed along with my "Vehicle Alignment Report" for each Tire. I got to meet Gregg the owner, I'm so pleased with his transparency. I feel they genuinely care more about the customer satisfaction experience then trying to upcharge sales. I highly recommend, plus he also honored my AAA discount. read more

Excellent customer service! Gregg and his team go above and beyond every time, friendly and helpful, like the good ole days. I wouldn't go anywhere else for any automotive need. read more

My husband and I were traveling through the area when our car broke down on a Sunday. Jeff and the team at Gregg's diagnosed and fixed the issue by the following afternoon, and we were able to make the 7+ hour drive safely home. THANK YOU to Jeff and the Gregg's Mobil team for your prompt, courteous, helpful service. You saved the day! read more

I've had my car serviced for general maintenance and for tire repairs to the rim. The entire group is so helpful and thorough with their work. Great customer service and the quality of work is top notch! read more

Gregg's has been my go to place for gas and automotive service for almost 30 years. Always fair and competent, also consider Gregg's Mobil for your tire needs as well. They can source any tire and do an excellent job of mounting and balancing. My highest recommendation! read more

Great service Honor appointment times Very friendly Will take all our cars great job read more

I went to Gregg's Mobil to get a break fluid flush on my car. About a month later I was driving my car and I noticed that I needed to push on the break all the way down to be able to slow down my car. I had my car towed to another car mechanic because I did not think that my car was safe to drive. This car mechanic fixed the problem by doing the break fluid flush again. He said that the break fluid flush that Gregg's Mobil did was not done correctly. read more

I take all of my vehicle to Gregg's Mobil for service and repairs! They do great work at a fair price. I believe Greg to be an honest and trustworthy person which is getting harder to find these days. Jack is always easy to deal with when scheduling my vehicles for service. I will keep coming back to Gregg's Mobil! read more

I had a minor repair and it went well. They noticed I needed a couple of tires and that was helpful. The customer service was great as always!!! If you are looking for an honest mechanic go to Greg's Mobil. read more

This petrol station has good hours, reasonable prices, and prompt service, making it a convenient and safe shelter on the hill. It's my first pick, and it's accessible from both directions. The experience is made much more enjoyable by the charming and amiable man behind the counter. read more

The time posted needs to be fixed. They close at 9 on Sunday's and at 10PM Monday-Friday. I don't know why the sudden time change, but please fix it on here. read more

They sell a package deal which includes a few services including a oil changes and other things like. The whole thing is one bog scam. They always find things to charge you for when you go in for the service that you already prepaid for. The most recent is $16 for an oil filter, yes you saw that correctly, i had a prepaid oil change voucher but they charge me an extra $16 for the oil filter. I would highly advise anyone to stay away and watch out for the typical scam about all other other things they find wrong. read more

Couldn't ask for more. Incredible ownership, quality service. Best gas station in town.

My fourth time at Gregg's to take my wife's car. Each time I was convinced of this review. Harder to find good honest car mechanics these days. Excellent communication throughout diagnosis, everything that I paid for was promised and delivered. Highly recommended! read more

I just had my daughter's truck repaired here. Gregg, Jeff and Travis were so knowledgeable and took the time to to explain what had to be done right away and what could wait. The cost was substantially less than what the dealership quoted me. When I went to pick up the truck, there were no surprises or upsells. I will definitely be returning here next time I need service. Highly recommend! read more

Gregg's is awesome. I came in with an appointment for oil change because my screen said low engine oil. Gregg asked when it was changed last time. I had no answer and just stared. He searched and actually found the sticker, and told me it did not need an oil change this time. Gregg added oil, saved me $$$ and even fixed my tire pressure for free. I was done in 10 minutes and only charged for the quarts of oil. It's great to have such an honest reliable business in the community. I know all my cars are coming here in the future. Highly recommended! read more

Integrity and customer service! 2 characteristics that Gregg's Mobile exemplifies. They've been the go-to mechanic of my family for 20+ years and for good reason. They are very candid and conservative when making repair recommendations. For example, I got an oil change in Santa Monica and they recommended about $1,500 in "urgent repairs" (struts, brake pads/rotors, wheel alignment, air filter replacements). I was suspicious of the validity of their recommendations, so I took it to Gregg's for a 2nd opinion. Rick and the team recommended the wheel alignment (at half the cost of my other estimate) and offered a few pointers of signs that the brakes/struts could need more attention. They are also very focused on creating a good customer experience. From text notifications alerting you to the status of your car, to friendly faces and positive attitudes that greet you. I HIGHLY recommend Gregg's if you're looking for a trustworthy mechanic! read more

Been using Greg's Mobile for 15+ years. Have never been disappointed in their service. A bit on the high side, BUT have never had to bring vehicles back after they fixed the issue.... First Jack and now Jeff run the day to day operation, but Greg sets the tone and policy. You will not meet a nicer man who has the utmost integrity than Greg. read more

We have been taking our cars to Gregg's Mobil since we moved in the area (over 13 years)! They are so honest, reliable and nice to work with. They NEVER over charge or over sell - they are amazing! The work is excellent and the service area is spotless! I can't say enough of how we are impressed with the work and the staff - 1st Class all the way! read more

Friendly, quick, helpful! Have had a smooth experience both times I've brought my beat up gas saver.

Thieves!!!!!! I had my car towed to this shop (referred by AAA). Jack (I think was his name) was trying to explain the problem my car was having but me not knowing what any of what he was saying meant, I had my friend who is a mechanic talk to the guy to get a better understanding of the problem. Especially because I was given a total of $1200. Once he talks to him my friend called me and said that it was ridiculous how much they tried to rip me off for. The total cost now since I'll be taking it elsewhere is $500. When I called back to Jack became very RUDE after telling him I was basically going to take my car elsewhere. He eventually hung up on me like a real asshole. Get a second opinion before getting work done here!!! read more

I've been taking my 2000 Toyota Solara to Gregg's Mobil since 2012 and I'm always really happy with their service and their work. Gregg and Jack are fantastic and are great at communicating what needs to be done, work is done promptly and they keep my car running great! Couldn't recommend them more~! read more

I have been coming to this gas station for repairs for my car and my families car for over 20 years. I know I can count on them always being honest about the work that I need to have done and reasonable in price. It means a lot to be able to trust someone when it comes to the vehicle that I drive every day! Greg and Jeff and all of the staff are always kind and helpful! read more

Consistent, Honest and Trustworthy We have been loyal customers of Gregg's Mobil for more than 20 years. Gregg is the most honest and generous man in the business. They will tell you if something is needed and will also let you know if they believe it's not needed. We highly recommend Gregg's for your car's service. read more

I have been having my cars serviced at Gregg's Mobil since the 1990's. I have always been satisfied with their fine service, but MOST IMPORTANTLY I trust them completely. I originally met Gregg at Saddleback Church a long time ago. read more

Considering the cost of living in the areas surrounding this gas station and the prices, though considerably higher than average, are lower than what they could conceivably charge. The people working inside the mini mart have never been anything other than friendly. read more

Great people. Friendly and helpful. Trustworthy. LookIng forward to working with this station and service moving forward..

We have had our 2 Honda CRV's serviced at Gregg's Mobil for 9 years. The work has always been excellent. And FAR more importantly, we trust Gregg's Mobil completely. read more

Awesome people ... awesome place ... Gregg is amazing ... we've been coming here since 1997 & they always have competitive prices too.

Stopped for gas 10 min ago. Pumped a full tank no problem, but the whole time i was fueling the smell of gas was so strong I could feel it in my throat and the fumes were so strong that by the time i was pulling away my right lung was hurting. True story What was going on there today?? read more

Steam or smoke started coming out from under my hood when I stopped at a traffic light. Based on prior experience and great service, I immediately decided to take the car straight to Gregg's Mobil. Although they were quite busy, they were able to get back to me in a timely manner with a diagnosis of the problem (radiator needed to be replaced) and a competitive price estimate. My car was fixed quickly and at a price lower than the estimate! Good communications - John was great at keeping my informed! Great service - my car was fixed promptly, correctly and at a fair price. Trustworthy - I always feel like they are fair, friendly and knowledgeable. read more

My wife and I and sometimes our kids have used the service's from Gregg's Mobil for more than a decade. They are trust worthy, competent, customer focused and I never had to take the car back a second time. I truly prefer going to Gregg as opposed to the dealer. The staff is great, Jake the service manager and the technicians and even Gregg the owner. Thank Gregg's mobil. read more

I was brought to this station using my upside app. Thinking the pricing was at an affordable Low. I was amazed at how off the price was. I was going to fuel up a bit and changed my mind due to the lack of customer service. I didn't even get gas here I was so upset. I thought the customer service was poor. Seemed like the supervisor & employee did not want to be there. I've learned to double check prices before driving to location. So 2 months later. I thought I'd call to confirm price I have on upside app. The employee was clueless. Then said he's w a customer. I asked if I call back in 10min can he please let me know. His answer was "if I have the time". Wow guess they have a consistent flow of regular customers and have No time for new ones. Customer Service does not exist here. Over all review 0-10 (10 being the best) they get 0.01. I'll giv some credit just because the employees show up. read more

Gregg and all who work with him are honest reliable and do an excellent job with any vehicle repairs. Pricing is very competitive and you know you will get the job done right. Very good place to get your vehicle repaired read more
