My perspective.
I don't think rolled fenders or properly removed A/C would help or hinder a nice car, especially if all a/c components were provided intact and presentable. If someone wants a car with great A/C, they should buy a late model Toyota, not an aircooled 911. This was the first line of price beating everyone trying to buy my friend's very nice '83 SC had, "How cold is the air?" It's not cold, never was, now go annoy someone else.....
