G'day Roger,
I know where you are coming from.
I too have been a witness to the Sale Photos and what actually arrived Photos, and if only I was able to physically see the vehicles in question, I would have left them well alone.
But, what Americans consider as "Repairable Rust", most of us "Sane" outsiders, wouldn't even contemplate.
But, if we had to buy a good car, it would never get purchased, even though the "Rusty" Cheap car costs more to restore or fix up in the end.
Bruce. 
You are right, Bruce! If I had see the car, I would have run back home! Halas, it was too late: the car was there, totally mine and at that time, with transportation and customs, too expensive to throw away (about CHF 10'000.- or $ 8'000.00). Resell parts? which ones? there was nothing good, except the outside windshield's moldings.
Anyway, I did not bought that scrap on basis of the pictures alone: I friend of mine, Don Bedford, let send an inspector from AA Technical Services to see the car, at my expense, of course.
His report was more or less correct, except that instead of "corrosion" I would have written "rust hole". The recap of his report is interesting:
"As can be seen from the contemts of this report, the main structure of the car is sound, with very little damage other than corrosion and general deterioration to the body work" This inspector was also a very optimistic man!
I'm glad you like the description and the pictures, I will post more. And sorry for my far from perfect English!
