20: Mini Cooper
The Mini Cooper was extremely popular when it hit the market in 2001 to much fanfare. As the years went on, however, time has not been kind to the mini. Consumers are more interested in other vehicles such as crossovers, which means the Mini is an endangered species. The Mini Cooper is, however, one of the most affordable turbos that you can buy new.
Mini Coopers are notorious for having reliability issues, so keep that in mind when you’re purchasing one. The higher the mileage, the more you’re going to have to spend on maintenance. But if you can find a well-maintained used Mini Cooper, you’ll have a blast with these little turbos.
