Walmart, Lincoln Fields. I found one 2005-era "Torpedo" car on the pegs. This was back when Mattel was fiddling around with weird non-standard things, like "Toon'd" and "Hard-Nozed" cars. None of those experiments particularly took, so if there was going to be a 2005 reject floating around it doesn't surprise me that it is one of these nasty things.
