So before the new Mercedes SLS Roadster hits the market, they’ve shipped one over to Dubai, apparently, for the tennis star Roger Federer to have a go. His comments are a bit cheesy to be honest, but whatever he says about the car’s power and performance and pleasure are absolutely true. The only thing we don’t like about the SLS Roadster is that chrome fuel filler cap. Why, why would you need that, it’s ghastly. Hope that’s an optional extra for idiots and not a standard feature of the car.
