The company I work for leases their vehicles for 3 years maximum. That means the lease company have to dispose of 6000 vehicles and that is just from one contract. Lease companies will have 100s of contract running at the same time.
As a rule my vehicle will have less than 20,000 miles on the clock and have only one owner along with full service history.... Ideal for a car supermarket.
Sometimes they dont even own the cars they sell.
I went to one and told the salesman the car I had seen on ebay was better value than his. He asked to look at the listing and checked and told me he could sell me the exact same car - which he subsequently did.
No chance of wriggling out of the price promise either.
the two dealers were not connected.
I think that they are mainly ex lease cars, say when a company leases a fleet of brand new cars and the lease is up a car supermarket will usually buy the fleet at a good discount from the lease company.
we went to glasgow from northumberland in oct 2006 for a car which even though we had to travel was a great price, the car came from another motorpoint and i had it for over 6 years until i reluctantly updated
