TCC’s Bottom Line
The 2013 Audi TT RS is the star on track, but all TT models offer fun and efficiency, plus a welcome dash of style. The 2013 BMW Z4 is spirited and purposeful, and balances fun and comfort quite well, but it's pricier than other roadsters. The 2013 Porsche Boxster is one of the most fun, stylish, and luxurious roadsters available.
