Thats what im on about - you can only drive a deal on what you know, and what I know is for instance if my car is traded in for 21k, and it can be sold for 24k with no work required on it then they will make 3k which I can drive a deal on when it come to a new car. Saying that if you dont have a part exchange you get a better deal is implying that you get less of a deal with a trade-in, which is misleading and goes against the logic which I have just explained above But each to their own - some people have different experiences, or they just have not used a trade-in option as an effective bargaining tool in their negotiations
But the point is, from the dealers point of view, they MAY make £3k on your PX. But that assuming they can sell it. It may sit on their forecourt for 12 months losing perhaps £300 per month and therefore any profit to be gained on your PX. They may even end up making a loss on it. therefore a PX deal involves more risk to the dealer. A straight cash deal means they make a profit, end of.
