Aye, looks tidy enough. Deffo worth more than £500, but like I say, if that's all he wants for it I'll take it off his hands.
One question, why does it need new bonnet lifters ? I think 1 - 1.5k tops is about right, a mint or restored campaign will go for well over 3k. mk1 tintops can be hard to price as they can go for all sorts of money.
