You have heard of snow, ice, rain, mud and sand, you do find them on the open road you know.
Glad to see your default impression of Porsche is speed though, that reinforces my desire to purchase one. :-)
Thing is the 911 Dakar which is ideal for the above mentioned conditions doesnt come with a towing eye, so I'd have to have the surfboards on the roof rack or poking out through the sunroof, and I've got no where to tow some jet skis if I wanted to hit the beach but you can do anything you like between the high and low water mark on a UK beach and I know some fantastic beaches perfect for this car.
