Here is one technique if you are not using dealer financing (paying cash or have already made arrangements at your bank, credit union, Uncle Willy, etc.). Make the deal, write out a check in front of the sales guy/sales manager, whoever. Hold the check in your hand and simply say that is the total to the penny you are going to pay them, period. If they balk, tear up the check and head for the door.
Always have "extree" checks! Most of the time, they will come a runnin'!!
Isn't it a shame that we are reduced to these tactics when dealing with so many of these folks? Buying an everyday vehicle or an RV should be an exciting purchase and time, not reduced to a an experience of grief, anger and frustration.
Our last RV purchase was from an individual and boy was it a pleasant, coffee drinking, story telling experience. Why don't dealers learn? Why don't sales people educate themselves? The individual seller and I came to an agreement in fifteen minutes and we went to the bank and completed the transaction. That was after I inspected his almost new unit with a fine tooth comb.
