Here's a rather interesting conversion for a Porsche 911. This cabriolet version gets a central driving position, which is obviously inspired by the McLaren F1. However, this Porsche 911 Cabrio is a single seater. The car underwent extensive modifications, including chassis mods, steering column conversions and others. This Porsche 911cabrio is currently a one-off prototype, but we're there will be more attempts of creating a central driving position 911 from now on.
