<prompt> Human: I have been contemplating purchasing a new to me vehicle, for under 15k. I received an offer from Amex for 0 APR through July for a set of charges of my choosing, up to more than would be needed to purchase the car. I could pay off that amount by July without issue.Does this seem like a wise idea, or is there something Im missing?  <response>: Most dealers will only allow you to put roughly 3K on a credit card as they dont want to pay the additionally processing fees.
