TCC’s Bottom Line
If you want a light and lean open-top sports car that's fun at legal speeds, the 2013 Mazda MX-5 Miata is it--and it's reasonably practical. While the performance-per-dollar value of the 2013 Nissan 370Z remains largely intact, enabling it to play with more expensive sports cars for less money, rising prices narrow that advantage. The 2013 Porsche Boxster is one of the most fun, stylish, and luxurious roadsters available.
