TCC’s Bottom Line
The 2011 Audi TT straddles the line between sporty cars and true sports cars--or is it the DMZ? The 2011 BMW Z4 is an exhilarating sports car, and one of the better choices for touring, but next to other roadsters it's pricey. The 2011 Porsche Boxster is a fun, attractive, and capable roadster-everything you want it to be.
