If I financed my 08g35x sedan and still have an outstanding loan over 10k, would it be a smart idea to trade it in for a 09 g37 x coupe? actually, if I wanted to do it, how would I go about it? Any tips? Any other suggestions? I have always loved coupes more than sedans, and the fact that it also comes in an AWD for the snow here in the midwest, it seemed like a decent idea. Thanks everyone!
