Mini Cooper
The Mini Cooper was always a car with a distinct reputation. When it was reintroduced to the U.S. market in 2001, there was much fanfare. The car got a new following and proved to be a sales success. But the Mini Cooper was never touted as the most reliable car on the road (via Readers Digest).

Not only were the insurance costs for a Mini Cooper high, but the reliability was also questionable at best. Whether it was the head gasket going or the transmission going, the Mini Cooper was not cheap to keep on the road. The car was able to maintain a reasonable resale value, but that doesn’t mean it’s worth it.
