Tesla Roadster; $89,000-$100,000; www.teslamotors.com
I've never been into cars: They're too bulky and a big waste of energy. But I recently read about the upcoming Tesla Roadster. This is one cool car - it's compact and sleek, and goes from zero to 60 in about four seconds. It has regenerative braking technology that's perfect for hilly San Francisco, where I live. Even better, it runs on lithium-ion battery technology, making it light, safe, and virtually maintenance-free. I just love the thought of a sports car that's truly eco-friendly.
