GM will be "thinning the herd" of its Heritage Collection at this year's Barrett-Jackson auction, beginning January 13th in Scottsdale, AZ. As many as 250 historically significant cars, trucks and concepts are slated to go under the gavel, a few are bound to be sold well under their true value, and wise bidders are planning ahead for just such an occasion. It seems that the auction house will not be providing specific information on many of the models ahead of time, even if they may differ from the production cars they're based on in significant but unseen ways. This being the case, a few savvy shoppers have retained the services of Mark McPhail, the recently retired manager of GM Performance Engineering. Perhaps we should keep him on speed dial ourselves, ya know... just in case.
