Another 2 40th anniversaries just sold at Mecum, a 4,000 mile car for just shy of $90,000 and a 12,000 mile car for just over $50,000. I think the 12k buyer got a better deal!
The one at Barrett Jackson was actually $127,000 including the buyer fees (Mecum reports their results including fees, Barrett doesn't)

I recently put all public ZR-1 sales for the past year in a spreadsheet, and while I certainly wouldn't take this information to the bank due to relatively low sample size, I was surprised to find that on average a non-40th anniversary car is worth a 21% premium over a 375hp car, which seems pretty reasonable; however a 40th anniversary car has sold for a 48% premium over a non 40th 405hp car!

I'm not surprised the 40th anniversary carries a premium, but ~50% over mechanically identical cars doesn't seem very logical. It is the car I wanted though, as I love the color combo, and while there were similar exterior colors offered, there was no similar interior (which was really the draw for me) Also a personal thing, but I like the old style seats better and 93 was the only year for the old seats with the 405hp engine.

As far as rarity, yes 40th anniversary cars were 55% of 1993 production, but still only 3.5% of overall ZR-1 production so it's not very common. Though there are 11 colors that were even less common... Over 60% were bright red or black.
