Roadsters are a shrinking segment in the new-car market, with only a handful of models left. Buyers could opt for the current Chevrolet Corvette Stingray Convertible, Mazda MX-5 Miata RF, or a couple of other high-performance models from Mercedes-Benz and Aston Martin. The Miata RF is the cheapest of the bunch, but if you’re looking for a little more power, or even just a way to stand out from the common rabble at your local Cars and Coffee, you’ll have to look to the used market.
