A Camargue has a kind of novelty value but not too much more. Technically they are the same as a Shadow and were used as mobile test-beds for the improvements that flowed on to the Spirit. Each was hand constructed and no two are the same so parts prices can bight like a rottweiler and resale prices are low - especially in the US.
I have not yet seen one that is not full of rot - although this one may be OK. The best one I have seen belongs to a Club member who is truning it into a rat-rod. I am a purist and for me to say that rodding a Camargue is a good idea shows what I really think of them.
However, if a solid one came along with a low price I would probably grab it as they will go up in the future as most will be in the bin soon.
