ive had my car since 2004. The only major problems ive had is the alternator has gone out 2x. small things like the part that runs the heater is going out but I heard that happens because the part is only good for 100,000 miles and I have 137,000 miles. I have had issues with the chain that runs the supercharge engine. It keeps falling off and now the pulley that runs the engine has broken off...

Bought this car with 22,000 miles in 2004. I love my car, would never trade it in, unless I could get another one!! Starting to need some repairs (150,000) but nothing out of the ordinary. I hope this one runs forever!!! My sons are constantly arguing who will get the car when I can no longer drive, LOL!
