I think it may have been discussed before, but does BEX 1090 have a very unusual curve from the hood to the grill opening? It seems to be very rounded, much more like some of the Ferrari Barchettas.
One (not) down,BEX 406, three to go:

Interestingly the same car sold by Bonhmas at the Quail in Aug 2013 for $286k, said to be 256k euro at the time.

Of course currency movements can distort things, but its roughly +50K Euro in 2 years, or +20%. Considering what has been happening in the overall Classic market thats pretty average I would say......

BEX 222 did not sell, perhaps buyers were nervous about this last sentance in Bonhams desrciption - " It should be noted that there is another AC Ace in Denmark with same chassis number"
