Thanks for the replies and the links.
Now I wish I could re-title my post.
What I was hoping for was information on /specific/ dealerships or sales places where credit card sales were welcomed.
Judging by the contentious nature of some of the stories about CC use for card purchasing, perhaps this might not exist.
So...if I were looking to buy a new Tahoe hybrid, anyone got a specific dealer I might contact to use my CC without having to resort to quoting the contract language?
