Dealer business flexibility?!?!

Ok a bit of a long shot but I thought someone in the know might have some input on this.

I am wondering about how flexible dealers are to do deals on 2nd had stock, for example if I went to a dealer to look at a 2006 X5 and brought my 2007 e92 along, could I negotiate a swap without money exchanging hands. I'm pretty sure the e92 would have a higher value by approx 1-1.5k but would I be dreaming thinking that I could do that kind of deal? I still have an outstanding loan balance for the e92 too, which I would continue to pay off!

Any thoughts or input?

Car dealers dont do swaps with the public. Thier always has to be money their way regardless if your current car is worth more.

The only way a dealer would swap, Is if it was well in their favour, Family Diesel for a big hard to sell V8 etc...

Better off sell the E92 private, (Carzone, DoneDeal etc..) And walk in as a cash buyer and see how much you can haggle off the X5.

Very tough to do generally and a dealer will have a very limited market for your car as well...also, is the money you still owe a personal loan or is it a HP/PCP arrangement?

If you have finance on the car the dealer will need you to clear that before even entertaining a deal. Some dealers will deduct the amount you owe from any deal and pay it directly to the finance company. Ultimately you will end up forking out something.
