bigkev, the Smart car is rubbish (I know, plenty of them on the road) but the Smart Roadster is AMAZING! It's got an engine smaller than my mini but it as the acceleration of a top-range sports car. I want one.
Not a British company, just the British distribution, it's originally a Swiss design. It goes great up hill, and when you roll down hill you get some back charge.
Actually my girlfriend loves riding in the Twike, she preffers it to a normal car, so do I, means I don't really care about the price of petrol and it's environmentally friendly. :D
