I know that I have an interest, BUT , when was a convertible last sold ?
The last I know was the car that JD classics had and I think that went for £120k.
From experience of other marques , I think that many of the values quoted in that guide are for dreamers . About a year ago , I sold an Aston through a dealer for double the price that guide stated .
Another AC example in that guide suggests £24k for a concours Greyhound ? The registrar suggests £65k
Enough said .
