My fiance asked. The dealer said yes and even doubled checked to verify there wasn't a 3% fee for doing so (like when paying your taxes with a CC).

However, I still don't believe it.

I have the cash to buy a new car with financing (and will need one before the end of the year) but how can a dealer justify the expense on such a large purchase?

Surely, I would love to buy it with my Starwood Amex or perhaps even sign up for the Delta Amex if they have double miles on all purchases.

Does anyone else know or perhaps even bought a car on a credit card without incurring any additional fees or dealer mark up?
