These extra special incentives and 50% off deals on new absolutely kill the trade-in value of the used models in the market. I had a guy fax me one of those deals offering me 3% over dead cost and he wanted me to give him 12 grand for a trade that may have been worth 5. Offered him the 3% over deal but I wasn't going to eat his trade. Needless to say I never got the deal. I saw him the other day prowling the lot and he still drives the 5 grand trade.
