Cam shaft broke, the engine was knocking.
Radiator had a crack.
The engine light would come on.
The car is a cute car, but it has been a headache since I bought it.
The engine light thing has occured to me when I was getting the car back home the same day I got it from the dealer. After all it turned out to be a problem with a single wire from a MAP sensor to the computer and replaced under warranty.
