18: Mini Cooper
The Mini Cooper experienced a resurgence when it was revived for the 2001 model year, and since then it has remained a unique option. But the Mini Cooper is a complex car to own and repair costs can be expensive (via Hot Cars).
Even an oil change in one of these automobiles can break budgets, especially if you are doing it at the dealership. In recent years, its transmission has also been the subject of many problems with owners, and it’s not a cheap fix.
