Are there good 911s for £13k? ...

Of all the cars you're looking at, a 3.2 Coupe with a G50 box and preferably '88 or '89, as people like as late car as possible, will be the easiest to sell, although I suspect you'll fall in love and won't want to sell.

I did sell my GP white 3.2 Targa but I have to say that it would have been much easier in any other colour - currently white is not very liked.

I understand Rubystone's non-spoilered preference but I don't think that it will affect sellability and the spoilers do improve stability at high speeds (apparently - I don't speak from experience)
