#9: 2010 Nissan 370Z Roadster
More powerful, better looking and lighter than its predecessor, the new Z's starting sticker price of $30,650 qualifies it as one of today's great performance values -- even when you pay extra for the convertible (expect a starting price in the mid-$30,000 range). Its impressive list of performance credentials includes the world's first manual transmission with automatic rev-matching downshifts.
