I have been a customer off/on for decades. They are a good import repair shop, but there are caveats.
First of all, their pricing is quite high...as high as you would pay at a BMW or MB dealer. They can do this because they are good (but not excellent, they do screw up) and they really have no local competition. The closest import dealers are in Bay City/Saginaw and the closest BMW/MB shop is in Grand Blanc.
I had them replace an alternator and was charged the same for a rebuilt alternator ($500) as one can buy a new alternator for on-line with no core fee. The installation fee was a thrilling $700 with a $90 code reading fee. (My friends looked at me in shock when I told them that one.) They wanted $200 to replace a $20 glow plug. (I think their man was shocked when I passed on that one...did it myself, 30 minute job.) They will not let you supply your own parts, new or used, they want to make money on the parts which would be OK except they charge very high for parts.
They also do screw up on repairs. Years ago they tried to fix a power steering problem in a Lexus for me and after three failed attempts I gave up.
Bottom line is that they have been around a long time, are good at what they do (but not perfect), they are local (convenient), but they are expensive and they really need some local competition.
Someone had good things to say about another shop near Dow Chemical that does at least some import work and has more reasonable prices. May have to seek them out and give a try. read more
