2010 Chevrolet Corvette ZR1Enlarge Photo
Stupendously fast yet amazingly practical, the 2010 Chevrolet Corvette is the supercar you can live with. There's no ZR1 convertible, but even the "base" Corvette will send shivers down any NASCAR fan's spine--and give any 911 owner a reason to cross-shop with Chevrolet. Enthusiastic buyers get a new Grand Sport convertible option, with wide-body styling and race-bred suspension; all 'Vettes get a potent 430-horsepower LS3 V-8 that displaces 6.2 liters and is good for a 0-60-mph run in just 4.1 seconds with the manual or 4.3 seconds with the automatic.
Key feature: Launch Control puts the power of the driving gods in every 'Vette driver's hands; just switch into it, lay on the gas, and those 4.1-second times are yours.

Stunning performance is still the calling card for the 2010 BMW M3; the weight it's gained may just be a sign of its success. Though it's gotten heavier in this generation, and has switched to V-8 power as a result, the M3 remains one of the best-handling grand tourers available. In convertible form, its folding-hardtop mechanism flips out of sight in about 20 seconds, and gives coupelike sound insulation when it's raised. Priced from about $67,000, it's one of the rare sports convertibles that will carry four adults, though that back-seat space will be the butt of jokes once your guests extract theirs.
Key feature: BMW's dual-clutch transmission is pretty brilliant; HD Radio is on all BMWs and gives exceptional clarity to local AM talk radio even when the hosts themselves cannot.
