I have had so many problems with this car and I can speak to owning from the show room floor until now about 10 years so far. I have reached my last breaking point for us.

what do you do if you changed the pvc valve hoses and the car was running but won't stop now what s the problem Anthony of Houston texas
Contrary to other reviews this car has been extremely reliable. It has only needed oil, fluids and bushings. The power from the 184hp engine is amazing and transmission is as smooth as silk. The AC is surprisingly very cold and all electronics work great. The steering is tight and the car handles like a dream. The styling is timeless. All in all an excellent car.
