I was asking myself exactly this question a few months back. As many will have done I short listed the BoxsterS, SLK CLK55AMG & Z4MR & Tuscan. Needless to say I went way over my budget and am now the very deligted owner of an 08 Z4MR. I've previously watched one at Brunters doing 160+ and if the roof can take that kind of negative pressure, I'm certain it can take a foot of snow now and again. Go for it.
