Since the Mazda Miata launched in 1989, over a million units have sold across all generations, making it the best-selling sports car in history, and with good reason. The Miata is known for being fun to drive and adorable, all while having a convertible top. With its go-kart-like handling, the Miata is "always the answer," whether it's the track, canyons, a coastline cruise, or a morning drive to work. The Mazda MX-5 Miata recently made headlines for finally going over the $30,000 threshold — but it's still the cheapest new sports car available in the United States at $31,665 to start. However, you can still find a cheap sports car for cheaper if you're willing to buy one used.
