Want to help the environment, but don't want to drive a lame electric car that doesn't go faster than 55 mph? Or, are you just worried that your neighbor will see your go-green car and start calling you a tree hugger? Get the looks of a hot sports car, and save the environment at the same time with a Tesla Roadster. Its 2x more efficient than a Prius, and 100x better looking! Your Roadster can take you from 0 to 60 in 3.9 seconds. It's 100% electric, and has 288 hp. BUT (and notice that's a big but), a Tesla Roadster starts at $108,000. So, while you may be looking good and saving trees, you definitely won't be saving pennies. For less expenisive (but still hot) options, check out the Tesla Model S, starting at $49,900.
