Most dealers will not do this. Most will not even take a $5,000 deposit on CC because of the fee's they are charged. If they have 3% CC fee's and Amex is usually higher than that, they could be looking at $1,500 lost on the deal. My dealer doesn't take more than $2,000 on a credit card.
However, my Wells Fargo Platinum actually sent me a check book and allows me to write a check and use the credit card account as if it was a checking account. There is 14% interest if you don't pay it off in 30 days and each check gets a one time fee of $25. However I made a down payment of $25,000 and then paid it off right away. Netted me a nice set of airline tickets first class to Hawaii. Not bad for $25
