Audi TT

You like art objects that can whisk you down the highway at license-losing speeds. The Audi TT Roadster certainly qualifies: http://www.audi.de/etc/medialib/cms4imp/audi2/product/tt/tt_roadster/ttr_2006.Par.0039.Image.jpg

This is hands down the finest looking automobile to come out of the last decade. You know you've come up with a classic when the car you've created would look stylish in the 1930s and the 2030s. Sure, there are faster wheels, but who gives a shit? Once you've doubled the legal speed limit, do you really need to go faster? The coupe version is gorgeous, too. But buying a sports car that isn't a convertible is just stupid. If you're going to make an impractical purchase, go all the way.

The only downside to the TT, like all sports cars, is that 90-percent of the people who drive them are insufferable pricks.
