If you intend on trading in the vehicle you drive on to the lot, don't tell them that. when they ask you, "Is that your trade-in?", or "Do you have a trade-in?", your response is "NO". then haggle a price of the H3 and get it finalized and in writing. then tell them you want to trade in your car. Not really lying, you just changed your mind...like my wife does all the time
, and she doesn't get charged for it so why should you
