Price is probably what Len suggest if its in great nick. I got my 8V R reg in Nov for £1200, needed a bit of work, 1 year MOT, 6month tax, FSH.
If yours is in good nick and you fix the lights, £1500 maybe more.
You could advertise on fleabay but beware the charges are a b!tch.
One suggestion is stick it on fleabay, put your number on so people can contact you, come and see it then sell it off the books for cash. Just say it didnt sell. ebay will definately increase the number of people that will see it.
I saw the same thing as you on the trader BTW, people asking 2500 for a piece of s**t that was rusting while good Mk3s for less or even more (3000+)
