The Porsche Boxster is the sportiest competitor in the segment, and while you may deal with a little more interior noise, it's the best option for someone looking for occasional track use.
The Chevrolet Corvette is also plenty sporty, though it rides well, too, and its V-8 engine is both more powerful and decidedly more American than the four and sixes you get in the Z4.
The Audi TT feels lean and sporty—and it costs less, too–but it comes standard with front-wheel drive.
There's also the Mercedes-Benz SLK, which feels bulkier than the Z4, but offers engines that emphasize fuel economy or power.
