They ruined my transmission a few years back and blamed it on me. Took over 3+ weeks to get my car…read moreback. I eventually had to go to a junk yard and buy my own transmission for 1/15th of the price of their rebuild quote for them to install. They cut my exhaust pipes where the flange from the Catalytic converter meets the H-Pipe. Not sure why they didn't just unbolt it? In fact, didn't even bolt them back together with new bolts when they cut them off. Instead, they put on exhaust sealer/glue. When I got my car back, I told them that I had a big exhaust leak and their response was, "the car was like that when you gave it to us". My driver side exhaust has been leaking for years due to them cutting the flanges.. I had to grind down the flange just to level it out and it's still not perfect. Every week that I called them, they said never even started it. "it will be done next week, call us next week" - "oh yeah he just looked at it, call us tomorrow" - "give us one more day". How hard is it to swap transmissions? They replaced the oil pan on my transmission and charged me for it without my consent because "It had a dimple in it". I even had to take the car back to get the shifting lever re-adjusted because the car had trouble going into reverse. I never even got my old transmission back either. They wanted to charge me a "core" charge for my own transmission when they were supposed to swap it out with another one I had in the trunk. My car drove perfectly fine without 4th gear and overdrive turned off. Once they did whatever they did, I got my car back and it was slipping gears, only to lose all forward gears on the highway. They charged me to install the replacement transmission I bought at the junk yard. I haven't had a problem with that transmission after all these years. This happened years ago but I remember everything. I love how my review isn't recommended. Do yourself a favor and avoid this place.

Their March 1 repair record shows they replaced the rear subframe, suspension, and brakes. By September 1, the car broke down and a second shop found loose parts, an incorrectly assembled rear end, and front differential failure -- the same areas that had just been repaired. This happened within about 10,000 miles, indicating repair issues, not driver misuse. By October 1, the transmission also failed, leaving me with no vehicle.

The invoicing was absolutely flawless and I was charged exactly what was quoted. In fact, I paid less than quoted, considering the extra repairs done as a military discount! The warranty is very considerate and generous, right along the lines with what the dealership itself offered. Furthermore, I paid about $2,000 less than I was quoted by the Chevrolet dealership in Putnam, Connecticut. Upon getting into my vehicle I was blown away of the performance! My Chevy Impala drives like brand new with 155,000 mi on it and a brand new transmission and I am confident I could probably drive it another 155,000 miles or more!
