Like Mitsubishi and Toyota, Nissan also built a comfortable, turbocharged sports coupe in the '90s. The Nissan 300ZX lasted for two generations, but the later Z32 Turbo model is far more desirable. The twin-turbo 3.0-liter V6 produced 300 hp through a four-speed automatic or a five-speed manual. The turbocharged manual cars are the most expensive, but can still be found with very low miles for under $30,000. These cars are rising in value, but you can still get in before everyone catches on to this '90s gem.
