Not a dealer -- a collector car columnist. I'm also trained to be a concours judge, although I must admit that I've never put it to use...mostly because I've never enjoyed it, nor do I like the politics that come with judging.
I think you might have misunderstood me -- while there is only one value for concours -- a number one 99-to-100 point car, what constitues a concours car by owners, and even clubs, is all over the place. In this sense, we are in total agreement. My point specifically is that what appraisers consider "concours" is different than those who own, restore, sell, and now - very importantly judge for specific clubs and events.
I generally give an over-simplification of definition of concours-quality valuation: "if you spent $100-200K on the best quality restoration, this is what the car would be worth." Of course, I know people who have spent more on unique, rare and blue-chip car restorations, but this usually makes sense to owners of the Fords, Triumphs, Dodges and Corvettes. (They don't think it's fair, but, as a friend of mine who used to own VW Beetles likes to say "Beetle hobbyists will never learn, and never accept that no matter what they do to their cars, no matter how much they spend, their Beetles are still $5,000 cars.")
99-to-100 point TR3s are not as rare as you seem to think. Especially in the Pacific Northwest, where British cars were extremely popular since new. (The All-British show out here is packed with many concours-quality cars.) You can generally see at least 10 true concours-quality (and far better than new)sidescreen TRs in any given year. In some respects, TRs are one of the easiest cars on which one can do a concours-quality resto (availability of parts, size, removable frame and panels, and the fact that almost 100,000 cars were originally produced, most coming to the US.)
TR3Bs, okay, yes, they are not on every street corner, but certainly not really that rare (3334 originally produced -- and I know of a handfull of concours TR3Bs off hand.)
And again, I'm not saying concours TR3s cannot bring over $20K -- they certainly do on occasion, but they are outweighed by those that don't. I have seen over the last year 99 and 100 point TR3s (TR3As, not Bs, but TR3s, nonetheless) go for sale under $20,000 (not much under $20K, but under $20K -- and these were wire wheel, OD, leather interior cars -- one had a hardtop.)
#3 TR3s tend to be closer to $12K, although, again, I've seen them go higher, but I've seen more #3s go for $10,500 than $15,000. Most of the $15K sidescreens I've seen would be closer to #2 cars -- and have been competitive regional show cars.
There definitely is some regionalism, and Arizona definitely is higher for specific types of cars, British included, (but painfully lower on cars like late 70s Trans Ams.)
So...as an old business cohort of mine used to say "I think we're in violent agreement" on most everything, except for the actual prices. All I can say is that what I have seen with my own two eyes, plus the market guides I get multiple times over each year seem to place the values lower -on average.-
But if someone has a concours TR3, I hope they get more. (If anyone wants to buy my 80-85 point TR3 for $20K, let me know /ubbthreads/images/graemlins/wink.gif If someone here on the forum is looking for a concours TR3, I hope they get it for $6,000, and we'll all be happy for them. (Jealous, but happy!)
