It took faster than I had imagined and they even went above and beyond and cleaned inside my car! I recommend them now just because they helped walk me through the process and what not!

Not happy

My wife said when she came to pickup the car it ran the whole time she waited for it which was at least 30 minutes, she thought that was weird. It all made sense when she shut the car off, then went to re-start it, the battery was dead and the car wouldn't start, and the guys at the body shop had to know this, which is why they had it running. They thought they were charging up the battery with the alternator, but the battery was already dead. I had to drop another $230 on a battery. There are chips in the paint and it smelled like someone smoked in the vehicle, plus the side view mirror didn't get painted so I'm a little upset and disappointed.

Car looks great. Although it took some time to find parts for my old car, Tim kept trying. He didn’t give up when I did. Thank you Tim!

...but with one caveat: because the quality of the workmanship is so high, MVGMC is so busy that patience may be necessary.
