I've considered selling my 72T or trading it for a later 80s 911 many times. It's definitely a lot of work, which is a strain on both my time and chequebook. But each time I get thinking about it, something in the back of my head makes me think that if I did get rid of it, I'd regret it sooner or later. I picture myself when I'm older (I'm 32 now) saying 'yeah, when I was younger I had this awesome 72 911 with RS flares, ducktail, man was that car fun, shoulda never got rid of it!'.
I'm trying to learn at least one lesson the easy way.
