We went to buy a new SUV, trade-in a older car, but had it appraised first.
Salesman offered half -- we started leaving immediately. Salesman then ran out into the parking lot and doubled the offer ... said his trade-in guy made a mistake -- but we left anyway, because he tried to low-ball the trade, so we then don't trust him.
Drove tot he next dealer -- he also offer half value. We walked again, and he ran out into the parking lot, told us his trade-in guy made a mistake, and he doubled his offer. This was an instant replay - bizarre.
We went to a third dealer -- walked in and said: Before we do anything, we want a value on our trade first. We told him - ONE CHANCE - he came back nearly at our appraised value, so, we then negotiated a good price for the SUV and drove it home. In both other cases, the SUV we rejected due to the low-ball trade were HIGHER priced than the actuall price we paid with the real value of our trade ... when we compared the difference between our trade and the SUV we bought, we saved almost $5000 less total than on the first two that tried the 'low-ball trade. We drove the SUV home -- and are very happy with it and the price, and the trade.
Some dealers want your business for years and years, some want you last buck right now and don't care about anything else !
