MV's are ok, you need the 1000 rather than the 750 as the 750 needs to be revved way too much, and at the end of the day they're both just Suzuki engines! Personally if it was my money and i wanted a bike i'd get a Ducati 1098r (which is apparently quicker than the Desmo in real world situations according to mates who own both) or a Bimota DB5. As for the car situation i havn't heard of many problems with the Boxster (especially engine faliures!) anything other than a classic car is going to lose value, how about an original E30 BMW M3, you'll get a nice one for £12k, if you look after it it won't lose value and parts are pretty much readily available. You can probably get classic insurance as well, if the old angle doesn't appeal how about a E46 M3.
