This new Mercedes SLS Roadster review takes the 571 hp open-top madness around the British countryside. Even though it's not as dramatic-looking as the Gullwing version, the roadster is still capable of offering a sense of occasion when driving it. The lack of vertical opening doors is compensated by the raw sound of the exhaust, which makes you ears tingle when the canvas top is opened. Unfortunately, the 195,160 EUR price tag of the SLS roadster makes it unavailable for most of us.
