They're quite simple really. The dealer agrees to pay a stated amount for your car (usually after 12 months) so long as you don't go over an agreed milage (usually about 11,000) and that your car is not damaged etc.
It is not a case of many dealers being able to offer buy back deals at all.
How it works is you buy a car that has gad value retention for example.
You buy a BMW for Â£20,000 that is actually worth Â£25,000 due to your tax free status. A year later the dealers book price for the car is Â£20,000, what you paid in the first place so you simply hand the car back and take a new on our not if you chose, so long as you fulfill the criteria, no damage, belew the stated millage and so on.
Most cars are not in this position as they wont hold there value sufficiantly and will be worth less a year later than what you paid for it.
As a general rule you have to be in the market for a fairly epensive car in the first place.
Standby for lots of people stating "my car is on that deal" please note I did say as a general rule.
The truth is that buy back is used for the vehicles that are popular in the UK, but limited supplies cannot fill the market sufficiently. For example, the Ford S-Max was on buy back and this was subject to condition and less than 12000 miles on the clock. Other vehicles where buy back is offered includes those at the very top end of the executive range. However be sure to get something in writing as companies can change their minds half way through the year.
