6. 2012 Mazda MX-5 Miata
Average paid: $23,079
It has all of the performance of a Porsche Boxster, but about half the price. For two decades, the Miata has served as the roadster of choice for recreational drivers and retirees across the country by offering big fun and performance from a small engine. The little two-seater has only about 167 horses under the hood, but just enough zip for buyers more interested in the wind and sun than in smoking the Porsche a lane over.
