I've two, both purchased by me ~ 2006 when these were released.  One is as described, "Lightning McQueen", the other is and what seems to be "Dirt Track McQueen" in a series 1 blister card describing the car as "Lightning McQueen".  I'm not sure when "Dirt Track McQueen" was released in the second version of these cards (1.5?).  I'm trying to ascertain if this error has any value?  

Since I bought these, most likely from Target ~ 2006, this vehicle had been in my possession since that time.  I assume that this card had not been tampered with in any way prior to my purchase.    If you'd like I'd be happy to send you a picture, please let me know.

Thx, I look forward to any information you may have regarding this one!
