37: Ford Mustang
The Mustang was long considered the everyman’s sports car, but as time has gone on, the car has gotten more complicated. New technology has made the Mustang an even more expensive car to repair. Between the EcoBoost engine and the head gaskets, repairs on the current, modern Mustang set drivers back a pretty penny (via Readers Digest).

The transmission is one of the main failures in the car, and the timing chain has also been known to go bad on the V8 models. The Mustang isn’t the simple car it once was and you can’t work on it by yourself. The new Mustang is a modern vehicle with many computerized systems built in.
