Mine is the Jeep Visa, but the Chrysler/Dodge/Jeep ones are all the same (Chrysler Financial Visa, issued by Bank of America).
You get 1% credit on all your purchases, which can be applied toward Chrysler merchandise (clothes, hats, collectibles...), or you can convert the credits to 'Dealer Dollars', for use at a Chrysler/Dodge/Jeep dealership.
I put some toward the purchase of my 300C, and I just recently used 'Dealer Dollars' to purchase torsion bars for the Challenger!
Not a bad program, if you are sure that you will be purchasing something from a Chrysler dealer!
