Claiming the best value in the sports cars and convertibles category is the Mazda MX-5 Miata Grand Touring, an all-time favorite among sports car enthusiasts. Not only is the top-of-the-line MX-5 Grand Touring affordable at $28,345, owners get plenty of value with a fun-to-drive convertible. Under the hood is a 2.0-liter four-cylinder engine with 167 hp with a choice of a soft top or a power-retractable hard top. In addition, car shoppers can choose between a five-speed manual transmission or a six-speed auto with the five-speed offering 22 mpg in the city and 28 mpg on the highway. The six-speed automatic and manual transmission nets 21-mpg city, 28-mpg highway and it’s worth mentioning that the automatic owners lose a bit of power with 158 hp available from the same powerplant.
