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.

The 2011 Porsche Boxster is a fun, attractive, and capable roadster-everything you want it to be.

TCC Likes

Rev-happy engine
Excellent short-throw gearbox
Direct, quick handling

Awe-inspiring handling
Evocative styling
Strong acceleration

TCC Dislikes

Lack of crash-test data
Cramped cockpit
Noisy on the highway

Storage space is lacking
Road and wind noise annoy some
Sound systems are better, but button-riddled
