I have had not merely good, but spectacularly good, experiences at this repair shop. After my Audi dealer quoted me $256 to replace a halogen headlight bulb (supposedly because they had to pull the front bumper), I went to M-A Shell. They got the bulb within a few hours and did the job for $90. Not only that, but they also fixed my ashtray, which had been stuck shut for a year -- and didn't charge me for that! (The dealer had said that they'd have to pull the entire dashboard, and that it would cost me something like $500.) A week ago when I started my car the "check coolant" light went on. I turned off the engine and read my owner's guide for a few minutes, then turned the engine back on -- no more coolant light, but I drove to M-A Shell. They told me that my coolant level was probably down to near where the sensor was located and put some water into the radiator. No charge! And no recurrence of the problem! These guys are honest, smart and conservative.
