15. Volkswagen GTI

The GTI is perhaps the car that’s responsible for sparking the hot hatch revolution. Packing a turbocharged engine into a lightweight and affordable package was smart marketing. Volkswagen perfected it, and earlier models of the GTI are memorable. The later GTI models have been plagued with reliability and maintenance issues. Being a German car, maintenance costs are higher than average. If you can find a reasonably maintained GTI, you’ll be in for a decent riding car. But if you find a GTI that has been riding hard, all you are going to have is a project.

The GTI is one of many cars that can cost an arm and a leg to fix. When it comes to buying a used sports car, there are some things you don’t want to settle for.
