Tony and his guys have been servicing my car for 5 years. They are all extremely knowledgeable about cars (especially European cars, they have multiple certifications all over the wall), they always treat me (and my car) with the utmost respect, they always use OEM parts and they are always fair with their pricing.
I brought my car in one day for some routine service and was extremely impressed with the service I received. When I returned for something else a second time, Tony recognized me and greeted me by my first name and even remember what kind of car I had. This blew me away. When was the last time a mechanic remembered your name and your car after meeting you only once?
They are open long hours to accommodate people and they are always able to fit me in. I don't even need an appointment, they just fit me in somehow. And it's not because they don't have any cars to work on because everytime I go in there are always cars parked in the bays and people are always in the office (which has free wifi, satellite TV and magazines).
I've seen expensive cars from BMW, Mercedes, Porsche and I think I saw a (new) Lamborghini once. If people with expensive cars trust this shop then that's a great indication of how stellar the team is. Tony himself owns an e46 M3 so you know he's serious about cars.
Another thing to note is that they have allowed me to purchase parts on my own to save money (getbmwparts is an excellent place to order OEM BMW parts), ship it to them and then bring the car in for them to do the service. For example, I have busted many tires and they allowed me to order the tire from tire rack and ship it to them because the shops price would be more based on where they have to order it from. They have also allowed me to do this with a brake sensor.
I refer this shop to as many people as I can. I've referred my dad, two friends and a few people from work. Each and every person I refer is completely satisfied with the service. I live in Jackson and I happily make the trip to Hightstown because I don't trust any other shop with my car.
