All Challengers are exempt from the promotion, as are all SRT vehicles. While it may sound like a good deal, it's really not, as it is in lieu of all other rebates/incentives, and there is a yearly cap on the amount of fuel. If your vehicle uses high grade, the cost becomes $3.29/gallon. Then you have to tie it into your credit card. Too much hassle IMO, I'd rather take the rebate up front and buy my own gas at whatever price it's going to be.
