The Car Connection's Take
TCC Rating
8.2
8.2
TCC’s Bottom Line
The 2009 BMW Z4 isn't a lightweight, basic roadster anymore, but it's a comfortable and exhilarating touring sports car that leaves a lot of flexibility. The 2009 Mercedes-Benz SLK-Class combines the romance of a small roadster with grand-touring comfort, as well as the poise and performance of a larger sportscar.
