Love this team of technicians. We have a VW and Audi and they do great work at a reasonable price for regular maintenance. Open and honest discussions for what needs to be done now versus later or simply optional. Additionally they've done multiple iterations of modifications and performance work on my VW Golf R bring it up to stage 2+ with no issues along the way. Again those were done in a timely manner and reasonably priced. Highly recommend Pat and his team for all things VAG.

Very clean engine after oil leak!

Theeee ultimate place to go for BMW repair and maintenance. Patrick and Larry were awesome. I went in for a complete oil repair due to leaking issues and they returned my car in impeccable condition. I only have an after pic but I've had my SUV for 5 years now. Never cleaned the engine and I had burnt oil all over since the oil leak.... And look at it now! And this was done without my asking. Please trust this place!

We were new to the area and really just went off of online reviews to make a decision on who to use. After they fixed it, I had absolutely no issues when I turned the vehicle in at the end of my lease. They worked quickly, charged a very fair price, and were incredibly easy and pleasant to work with. What really stood out was that they also took care of a few other minor cosmetic issues, no questions asked, just to make sure the car was in great shape for the lease return. That extra effort was really appreciated. Great work, fair pricing, and genuinely nice people. I would absolutely use them again.

I did call the business first and they were quick to answer the phone, and they said they could do the job and asked for the make and model so that they could contact their supplier and would call me back. The next day, while I hadn't heard back yet, I dropped by the business anyway, because I was at the library nearby. Ramon greeted me and I explained the issue, and they were able to find the part and replaced the bulb quickly on the spot, and I was done in less than 10 minutes! I was very appreciative of the excellent customer service, and I'll be back.

I highly recommend this place…read more Tonight I create a Yelp account again to be able to give them five stars There were some pretty expensive works at my car, but just like the previous quote was absolutely the best one I got from all the garages. They do not charge unannounced fees and really deliver what they promised, even if it takes them more work. I've already been here with two cars and I'm always extremely happy with how good they take care of my car. If you're considering whether you want your team of mechanics, take care of your car do not hesitate, I can highly recommend them

They recommended 2 new tires and an alignment so we proceeded. It took a long time because someone had stripped the lug nuts on one of the wheels but they still didn't charge much for labor. Unfortunately, that evening the tire pressure was low according to the sensor but I didn't believe it until it became very low. I called and they said to bring it in immediately and moved us to the front of the line to get another new tire. They showed us the problems each step of the way and explained the options and made things right, even though it became very complicated. The outside is rough looking, but they clearly are very skilled and give great customer service.

I brought my 1994MY Defender with the 200TDi engine in for very routine maintenance and ended up needing a new or rebuilt cylinder head due to a mistake made by their mechanic for rushing a job. During the regular timing belt maintenance I asked them to perform a cylinder compression check on the engine. It is a relative simple procedure requiring removal of the four glow plugs. However, it is widely known issue that glow plugs on 200/300TDi diesel motors can be very hard to remove and require much patience, penetrating oil, and application of heat. I double checked with them before, and they ensured me they had much experience with glow plug removal. They ended up breaking off one glow plug and two others were frozen in a very short period. To fix it required pulling the cylinder head and either repairing it or purchasing a rebuilt cylinder head. They also made me aware that they were limited in repairs they could do to 200/300TDi engines due to loss of in house capability. The total for the job went from a couple of hundred dollars to at least $4k in parts and labor and no guarantee. To make things worse they recommended numerous additions and repairs which were totally unneeded in an attempt to "up sell" me on additions which were unrelated to my requested maintenance even after I gave them the complete past three year maintenance history. Most people who own these older trucks are basically garage Land Rover mechanics who know when to call BS on recommendations. I mentioned the event during a monthly local classic Land Rover owner social gathering I attended regularly and the members were not surprised and said "Dean has lost his way from his roots with classic Land Rovers and is chasing the upscale restomod crowd." I paid $300 for a diagnostic fee I ended up spending $400 more trailering my truck to a more reputable classic Defender repair shop with better 200/300TDi repair capabilities and repair warranty 100 miles south of their location. I do not recommend this location.
