As a street-legal, race-worthy car that will get you nearly 30 mpg if you treat it right, the 2008 Lotus Exige is in a league of its own. Lightweight, powerful, agile, and extremely quick, the Exige allows for blistering driving in nearly any condition. The addition of the even more powerful S 240 only ups the ante in the track-toy game, while the Club Racer goes all in.
