"SL originally stood for Sports Light, but it certainly isn't light these days. No matter, with a choice of engines you can chose just how quickly you reach terminal velocity, and which ever you choose they're all electronically governed to 155mph. That is plenty with the roof down. And what a roof. The finest folding hard top available compliments a beautifully elegant body that draws looks with the roof up or down. As long as you only need to carry one other person then SL makes a strong claim to being the best car in the world."
