You're absolutely right! You're small potatoes. He sees a one time sale with probably no repeat business. He'd rather pursue the hard dime than the fast nickel. He has probably been quite successful selling the big iron, and really doesn't want to be bothered. If it were me, I'd go immediately to the dealership, demand to speak to the owner and explain to him the whole situation. After he had jumped down the salesman's throat, and I'll bet he will, I'd thank him for his time, cancel the order and explain to him that if I had this much trouble purchasing, I couldn't imagine the problems I'd have with service, and go elsewhere. Believe me, there are a lot of dealers that would love to take your money.
