I wish Hendry all the best in his search. My advice would be however, to buy the absolute best example he can find, whether it was registered in Glasgow or Grantham.
As far as I know, the op isn't the type to spend hours welding up an old crock or have the facilities to do so in the first place. With that in mind, it can only be crazy to buy something that is beyond redemption - it'll turn into an expensive lesson if he buys one with the desired dealer sticker on the back window and no sills left or floor to weld new sills to.
But one must learn from experience and I look forward to seeing the pictures of the car when it arrives with shiny tyres and a bent MoT.
