The Karmann Ghia is clearly supposed to look the way it does; there's far to much effort gone into it (sacks on the doors trimmed to fit, chrome looking like new when the body doesn't, tidy engine and suspension drop). By continually suggesting that it needs repairing you either a) don't get it or b) are deliberately misunderstanding to provoke a reaction. If it's a, then as hfs mentioned, 'Because everyone is different' is all you need to know. If it's b, then as exigeracer mentioned, 'Leave the troll alone. He'll go away.' is all you need to know.
I think it's easily the best KG I've ever seen, and Reno, you're a numpty for selling it
