Make sure to question everything you are unsure of. There are no stupid questions or comments at this time. Now it is time to negotiate the selling price. Even if you want the vehicle very much, still do not let the seller know this. Be ready to commit to the deal if a reasonable price is agreed upon.
Cash is a great motivator in closing the deal.
In most cases a person who is looking to sell a vehicle will not turn down a reasonable cash offer. If the seller turns down your offer, either make a new offer or wait for a counter offer. After you make your initial offer, do not speak again until he answers. This may be the most awkward silence you have experienced to date, but it works. If the person does not accept, they will usually counter offer with a price in between the asking price and your offer.
