2010 BMW Z4

The previous-generation BMW Z4 was one of the first cars styled by the company's (in)famous design chief, Chris Bangle. While that car's in-your-face styling wasn't for everyone, the 2010 version dials it down significantly, with more elegant lines than its predecessor. The Z4 coupe is gone, obviated by the new Z4's folding hard top. Two models are available, an sDrive30i and sDrive35i, sporting 255-hp and 300-hp inline six-cylinder engines, respectively. The engines can be connected to a traditional six-speed manual transmission or to BMW's seven-speed dual-clutch automatic. Performance is excellent, with 60 mph in less than 5 seconds for the sDrive35i. Have about $50,000 handy before shopping.
