The Mazda MX-5 Miata has been a hit since it went on sale in the United States in May 1989. The roadster cost $13,800 when it was new 34 years ago, which is $33,310 today when adjusted for inflation. A brand-new one is cheaper, starting at $31,170 (the price includes the $1,185 destination fee), but sometimes you have to pay a premium to scoop up a bit of automotive history.
