The water pump was bad when I bought the car and was making a lot of noise. When I had this replaced, the engine was as quiet as a whisper.
The only thing I've had go wrong was the idle: whenever the battery is disconnected it messes up the idle. This had to be relearned at the dealer, even though the car is supposed to reset its self. A bit of an annoyance.
Air conditioner needs to be recharged.
Suspension is getting weak, mostly in the rear.
I had a tune up shortly after purchase to the tune of $425, but that was the most expensive thing I've had done, so far.
Every now and then when I turn the key nothing happens, so I expect to need a new starter here in not-too-distant future. I don't look forward to that because it means disconnecting the battery, which will upset the idle, and then the idle will need to be relearned.
Looks beautiful for it's age. People have trouble believing that the car is 13 years old.
I'm very impressed with the all the interior room. I'm 6 foot tall and can sit very comfortably in the back seat with the front seats all the way back.
Over all, I love this car. I would buy another one just like it in an instant, though I'd prefer a newer model for reasons of looks and handling.
Excellent car, either for a long trip or just a quick run across town.
