Hi mate,
Seeing as you're in Nantwich have you tried Dixies or Northwich Metal? They are both behind the Salt Barge pub in Marston, Northwich. Dixies is dirt cheap and if he's still there the old boy was a right laugh! The guys in Northwich Metal are a little more expensive, but still nowhere near the prices that the somewhere like Car Transplants in Crewe would charge. Northwich Metal is pretty big too and when I was last there they had quite a good selection of cars.
Hope this is useful,
Chris.
