27: 2003 Hyundai Tiburon
The Tiburon was not the most impressive sports car in its first generation. But from a budget standpoint, it was a great car. The 2003 model introduced a turbocharged motor and a new modern design. From the outside, the Tiburon was an attractive-looking sports car (via Forbes).
But its reliability was not the best at the time, and the Tiburon was panned for its cheap build quality. On top of that, the resale value of the car was minuscule at best, which meant you could rarely recoup your investment.
