AIUI, if you take Visa, you aren't allowed to advertise a lower cash-only price. So maybe they were freaked out about losing the ability to take cards. Also, I'd be concerned about a personal check for that amount. The last car I bought I put $2K on my miles credit card (the max they would take) and a check for the rest. They made me fill out loan paperwork anyways so that they would have recourse if the check bounced.
