I have had all of the same problems as everyone else. The windows don't work right, the console lid is broke, the ash tray lid is broke, the alternator has gone out, the brakes have been changed, the gas mileage sucks, and it idles rough, too. The mass air flow sensor has been replaced twice, the catalytic converter blew out, the sunroof has jumped track, and, at times, the electric fan won't shut off. (Even with the car turned off and the keys in my hand.)
I put about $3500 in aftermarket performance products on the car and bumped the 215bhp up to 285hp. Injectors, full Intake system, cat-back exhaust, mass air flow sensor, coils, wires, and other misc. bolt-ons is what it took for me to like the car. You'd be better off to put the body on a rear wheel drive frame and drop in a big block. It would be a lot more fun.
Theres a saying, if it ain't broke don't fix it...
