Its more than partially correct. I have been to several auctions, bidding isn't based off of times ran, its based off people bidding on the cars they want to own.
I am also guessing GM dealers care less about Sig 2 than real collectors. If you have ever been to a Mecum/Barrett Jackson auction, you would also know there is alot of phone and internet bidding.
I guess we'll have to agree to disagree. I believe auction time and date has a great deal of effect on selling prices. I also disagree that GM dealers care less about Sig 2 than real collectors.
I was able to track most of the Signature Series several years ago when I was somewhat infatuated with those trucks. The photo next to this post will reinforce that. 17 of the 24 Signature SSRs that were available for sale in 2003 were purchased by GM dealers.
Three appear to have been purchased by private owners, but who knows if they were dealer principals. I have been unable to track the other four, because the only method I had available to find them was to make phone calls when the trucks came up for sale, and from those conversations, get leads on who else owned them. I tried the various auction houses, but none were prepared to reveal buyer names. Bob McDorman was great to talk to, as were all the other dealers initially. Some of them became quite bitter with GM as time went by, largely because GM had devalued the value of Signatures by releasing the color for regular production in 2004.
I remember one particular conversation, where the dealer called me when he was ready to sell his Signature. He had a selling price in mind, and I had to tell him I had just purchased one for about a third of what he was asking. Not a happy dealer.
I was able to track original selling prices. Average selling price was $75650. McDorman paid $137850, 125000, 120000 and 75000 for his. Signature 25 sold to a GM dealer for $120000. Those prices are net, before buyer's commission is added. That's enough data to make me think that GM dealers had some interest.
I can't remotely predict what Signature 2 will sell for, but I expect that 30 years from now, if it has been kept intact and with low mileage, that it will price out like some of the first and last Corvettes. The last 67 Stingray, which was a basket case when it was found - a rusted frame with a VIN plate and a rusted block with the correct number - sold at BJ for $600000 plus buyers commission. It wasn't a particularly rare car, just the last one. If GM ever decided to sell Sig 1 or 24112, I'd sure like to be in a position to bid for one of those.
We can agree that there are a lot of phone and internet bidders at most auctions.
