Steve,
Yes, some facts are in order here to make the discussion meaningful. Specifically, recent sales in the market place (limited, obviously) provide a range of $1.0M to $2.0M for an original road car and race cars with no racing provenance. $3.0M and above is reserved for race cars with racing provenance such as LeMans, Spa, etc. Ronnie Spain's book is a good guide to which original cars have race provenance. Here, "racing provenance" is roughly defined as cars that were raced (not sitting on the sidelines as spares) more than just once or twice, in recognized premier venues. For example, racing provenance in this category of car would not include a couple of amateur weekend races at Riverside. However, racing provenance would include Daytona in the hands of Gurney.
This car is obviously beautiful and a rare gem, but it's not worth $3.0M. I'd guess a seller could be found at perhaps $2.0M.
Yes, these are big numbers but just because they're big doesn't mean there isn't a reasonably well defined market price.
