As always, the best service and honesty. I brought my mercedes 3500 sprinter van (RV) in for a couple of reasons. My breaks were squishy and there were warning lights on the dash and the cruise control was not working. I was quoted around 700 dollars for a break job only (its a dually) plus the electrical testing and repair. I got a call explaining to me that they found the electrical issue, I cringed thinking the costs were about to be more than I anticipated 700 ++ The repair was done, the tire warning, the cruise control and the break lights all working fine, it seemed that the electrical fix also sent a signal to the break system and I absolutely did not need a break job. they are so honest. I had my sprinter at a Mercedes dealership (out of state) only 1 month before (they replaced my wiring harness), i couldn't bring it back to Boston to repair. C and G's charge was only 400 dollars for all of the work, I trust C and G more than any dealership. I'll be back, you should too.
