I was only half-joking about the provenance. It's generally accepted that yours is one of, if not the, best Hawks around, so its value would be well above average. However, it could well be worth less in the hands of a subsequent owner, because then it's not "the Guy Mayers Hawk", it's "the EX-Guy Mayers Hawk" and who knows what's happened to it since it was yours?

I'd suggest this particular car discussed here doesn't have anything like such a distinguished pedigree and if yours realised £150K, this was more realistic at its original price.

Whatever price it eventually realises, it should be heartening to all current owners, no matter the condition of their cars, as they're ALL worth something!

As for being lined up with a French connection....hmmm.... smacks a little of the old "honey trap".... I've seen those films
