Hi Brad
Welcome, I too have memories of reading about your old car 30 odd years ago.
The cars have indeed gone up in value, especially over the last few years - most agree that they will continue to do so.
As the prices have gone up, cars seem to keep appearing - possibly driven out of hiding by $$$
Anyway, good luck with the search and I look forward to hearing a success story at some stage.
Cheers
PB
