You got a 1 only because it wouldn't allow me to do none!!I have never had such horrible service in my life, In the beginning all was well until I got my vehicle there. They had it for almost 2weeks calling saying its almost done maybe tomorrow several times. When I finally called and said enough is enough I need my car done today!!!! they called me back 2 hours later and said ok your car is done. I drove down the street which is where I work. I finished out my shift at work and left to go home. I didn't even make it home before I was stuck in the middle of the road had to be pushed down a side street. I called first thing in the morning and they sent a tow truck to pick it up after it sat on the side of the road all night, had my car another 2 days and it still is not driving properly not sure exactly what to do because I refuse to take it back to the same shop!!!! Obviously, they have NO idea what they are doing. I know that when my car down shifts that it should NOT feel like the transmission is going to fall out of the bottom of the car nor give me whiplash because it downshifts so hard, It also jerks really hard when it up shifts as well although not as much as the downshift. This was the worst $4000.00 I have ever spent!!!! I would never recommend them to an enemy, let alone a friend or family member.
