19. Mazda RX-7

Mazda was a company teetering on the brink of extinction during the nineties. But the company still managed to bring us one final RX-7. Just taking a look at the beautiful RX-7 exterior elevates a heartbeat, then you step behind that rotary engine. The RX-7 drives like pure bliss and the interior is one of the most comfortable in a sports car.

The RX-7 was rather unassuming to look at, which makes the car a definite sleeper. It has increased in value dramatically and will continue to be a hot commodity.
