Hi,
I bought an 8 Valve some months ago now. I too wanted a very nice one (i'm sure we all do), took me a little while of looking in the back of VW magazines like PVW etc. I found one after a few weeks and drove to Nottingham to get it.
FVSH 88K in the Rare Blue colour (metallic light blue-500 made??) with a lovely set of Brock German wheels and a sound system. They are out there you just have to look hard. My car was up for ?3750 eventually i had it for ?3000. It's still worth that as it's in better condition now than when i bought it.
Just make sure you do your homework first, have a really lengthy look over the car, check normal rust spots, which are bootlid, wiper panel on the front of the car, arches etc. Most VW's are sort of enthusiast owned anyway and people normally have folders full of stuff about the car. Old MOT's etc. Check through them all to verify mileage etc.
Hope that helps!
Good luck.
