I paid £1500 with bonnet boot and doors - still in primer (that was in 1998 mind you) I then spent a further £1000 having it seam welded and converted to accept 4x4 running gear then another £2500 on the paintwork and glass.
I did have it up for sale a while back as I was selling off all my new 500 gear but then had a change of heart and will now build it up into a track car with all my spares bits.
If you do a search on the rs owners club there was a guy a few months ago selling a bare in primer shell
good luck
