I'm driving to Italy via Switzerland in a couple of months in my coupe, wish I had a roadster... for the bits south of Paris.
Loved having a convertible in the States last year, perfect conditions for it in California. Too hot for it in parts of Nevada, had to roof up to get some AC goodness in Death Valley, not a UK problem! I personally wouldn't bother up North, but if I lived 1000 miles south of Blackpool I'd be angle grinding my roof off as we speak.
