One of the appealing things about the std CS is you don't have the compromise of buying say a Cayman or something more expensive as is normal with a 2 seater..
Losing that makes me think well a cayman would be as good a buy if not better, whereas the std CS has few compromises but looks a bit more special than the std gti... and while I am sure it will depreciate enough, it ought to be a more solid buy than a standard car..
