I bought both my daughters a Renault Clio each on my Amex (a couple of years apart), so it is definitely possible. It was before credit card fees were outloawed, though. I paid around £13k for each and agreed a .75% credit card fee up front on each purchase. Whether or not it will still be possible in the era of no consumer fees, I don’t know, but I’m sure if you agreed a slightly higher price with your dealer, purely unconnected with the credit card fee, of course, they would oblige.
