TCC’s Bottom Line
The 2015 Audi TT is quick, fun, and stylish -- but it skips full sports-car credentials in favor of a little more practicality. The 2015 BMW Z4 is on the pricier side of the roadster segment, but it offers a nice blend of comfort, sport, and technology. The 2015 Porsche Boxster is a relative performance bargain, combining everyday usability with a balanced chassis and sweet engines.
