TCC’s Bottom Line
The 2011 Mazda MX-5 is a back-to-basics sports car that you don’t have to drive fast to enjoy—and it has way more practicality than you’d probably expect. A great performance car that starts just under $30,000, the 2011 Nissan 370Z comes close enough to Porsche performance to make you wonder. The 2011 Porsche Boxster is a fun, attractive, and capable roadster-everything you want it to be.
