The Car Connection's Take
TCC Rating
8.0
9.0
TCC’s Bottom Line
The 2010 BMW Z4 has evolved into an exhilarating sports car with a marvelous folding top, but interior space is tight and the price is dear. The 2010 Porsche Boxster is a fun, attractive, and capable roadster-everything you want it to be.
