I found a Mecum auction for the Signature number 2 and yes it shows the gauge. It also shows a nice view of the waterfall badge and it seems to be not metal. Looks to have gloss paint in the lettering also. Wish we had a member here to confirm that has one but so far....nada....sigh. Wonder who has 2? 77miles?...wow!
Signature 2 is the most complete, most documented SSR in existence. All of the GM add-ons were with the truck when we saw it in 2010. All of the McDorman Signature SSRs still had the pewters, scrapbooks, cover, and various pieces of memorabilia. I still have a complete printout of the EBay auction bid sequence. I scanned and emailed Bob a copy, so hopefully it was with the truck when it sold. Mecum has no photos of any of the accessories, but they do have a list of what is included with the truck.
Signature Series Memorabilia includes SSR book and metal case, Limited Edition framed art print serial #2, Limited Edition marble base SSR models, autographed SSR model, SSR mirror with frame, Black leather SSR jacket, SSR pullover and new car welcome package
I spoke to Bob McDorman a few times long before he put most of his collection on the block in 2010.
I made an offer on Sig 2 before I purchased Sig 23, but he wasn't interested, said he was going to hang on to Sig 2 as long as he was alive. I also asked about Sig 4 at the time, but got a similar response, so purchased Sig 23, and later Sig 12.
In our phone conversations, it was obvious Bob was very bitter with GM for releasing the UV color for regular production in 2004. He had purchased 2, 3, 4 and 5, with the understanding that only 25 trucks would be available in the UV color. Signature 4 sold at his 2010 auction. Although this was a no reserve auction, Sigs 3 and 5 were bid up beyond where they could sell, and Mecum was caught with its fingers in the cookie jar. 3 and 5 showed up at multiple Mecum auctions, and never recovered what they would have sold for at the 2010 auction. Only Sig 4 reached 50% of McDorman's original purchase price. Mecum would have had to pay McDorman for the botched sales of 3 and 5, but his return was less than 50% of his original investment.
Sig 2 was auctioned at Mecum after Bob died. The selling price was a give away considering he originally purchased Sig 2 on EBay for $138000.
Assuming the $51000 includes the 10% buyers commission, the truck returned around $42000 to the McDorman estate - way less than I offered him back in 2006.
I hope it went to a serious collector, but it seemed to disappear after that auction.
