The following are out now, some more readily available than others:
No Fin Cruising McQueen (either in a single pack or two pack with Sally)
Bug Faced McQueen
Bling Bling McQueen - blue with rims
Dinoco Chick Hicks
Hydraulic Ramone (red)
flashback Ramone (red and white)
Other than the above posted listing, the others haven't been officially confirmed yet. No pics, no word from Mattel, etc. Maybe something at SDCC?
Did they ever make a Frank Combine die-cast vehicle or Mack (besides those big playsets)?
No Frank, but Mack has been released - although he's not a diecast, but plastic. His trailer does open to a playset, but I keep it closed and it works pretty well with the rest of the cars.
My son loves this movie. It's either Cars or Nemo that he wants to watch. I must have seen this movie at least 20 times already.
