As a dealer myself, I can offer a few things that work on me when it comes to bargaining.
Don't - Ask the dealer to “sharpen his pencil.” We've heard that one.
Do - Tell the dealer that you want to do business with his dealership because of the great things you've heard about it.
Don't - Tell the dealer “I'm out shoppin' for price.”
Do - Offer to deliver the tractor yourself or something that may save the dealer some expense.
Don't - Tell the dealer “I don't care where I buy” or that “you just want the best price.”
Do - Suggest that you may accept a service pack of filters, oil, blades, etc. instead of a lower price.
Don't - Go from one dealer to the next with quotes trying to get them to fight over the deal.
Do - Ask to tour the parts and service department of his dealership and let the dealer know you appreciate the commitment he is making to provide service for you after the sale.
As long as you're not obnoxious, pushy, or demanding, most of us are willing to bargain.
