I know I'm replying to an old post but thought someone may find this useful. I went to trade my dingy (Jeep Wrangler) for a new dingy (Chevy Silverado). The dealer gave me a trade price for my Jeep which I didn't like. I walked. I played the fact the Jeep was equipped for towing behind an RV. I waited for the last day of the month and coincidently the dealership was advertising a sale. I told them that I really wanted to trade but because I had the tow gear, I needed more money for my trade. The used car manager got involved, made a few calls, and I got two grand more than the original offer. Like I said, it could be a coincidence and they really needed to make a deal. Whatever it took, it worked for me.
