Yes you can win the raffle Challenger without being at the show , you can't win the 66 Cuda or the Mopar Cash or any of the other door prizes if your not there . Plus you have to be Pre-registered before July 1 to be in on the 66 Cuda .
PS yes they do check if you are there with the car you Pre-registered by putting you in a golf cart and making you show them your car .
