TCC’s Bottom Line
The 2012 Mazda MX-5 is a true sports roadster with great handling and fun at any speed, and more practical than you might think. Performance per dollar, the 2012 Nissan 370Z is a bargain, and it's quick enough in absolute terms to reach toward the domain of much more expensive sports cars. Stylish, fun, and capable, the 2012 Porsche Boxster is one of the best roadsters around.
