This car is 14 years old. Please do not expect ANY 14 year car, even a Mercedes, to be a "turn the key and go" kind of car. It will require a fair amount of care and feeding, no matter how good a car.
That said, it can be a great car to own if you're willing to invest a little time and effort. Much less than ANY Porsche!
If you're really in need of something that just starts and runs and never needs much in the way of repairs, spend the same cash on a late model Corolla. Yucky to drive, but works like a refrigerator. Just open the door, and it's there.
