14: Lincoln Navigator
When the Navigator hit the scene, it pretty much revived a dying Lincoln brand. But the Navigator is not the most reliable car when it gets up there in age. The Navigator has a lot of expensive technology built-in that can cause pain at the mechanic shop. Small things like the electric seats and the dashboard blacking out all the way up to the air-ride suspension going flat (via Readers Digest).
You will spend thousands of dollars to keep the Navigator on the road once it gets old and riddled with mileage. There are many positive attributes about this car if you can find a low mileage one, but those are few and far between. You’ll spend a lot of money just to keep an older Navigator on the road.
