As a follow up to this story, here's a PM I sent to Puppycat:
Brad -
You're not going to believe this one, but it's true. Remember the post you did about the eBay! H2H Olds set with the red GTO in place of the white 442? So anyway, I'm in the TRU in Annapolis today and I'm looking through the JL's. Lo and behold there is an Olds H2H set containing one green 442 and one red GTO. So I'm thinking, WTH??? Then I remembered your post and I'm thinking, wait a sec, what are the chances that there is another set out there with the same error car - is the factory doing some monkey business? But the GTO is from such an older release. (I didnt' buy the set) Later tonight I pulled up your old post and see that the 1) the item never sold and zero bids, and 2) the seller is from Maryland. I'm guessing that he figured it out, or was emailed about his auction and returned the set to TRU. Talk about weird!
