We have a friend with an immaculate I36 - it is very well looked after. It's quite a roomy, cozy boat that seems to do well in most conditions.
I can say, though, that I've seen a worrisome number on the hard in our area with pretty significant blistering issues.. but I don't know if that's a general thing or not. Chances are, on a nice one, that will have been dealt with already and properly barrier coated..
