I doubt the car manufacturers would like Motability moving to 4 years leases as this would affect the number of cars they sell. The manufacturers would most probably raise their prices and Motability would get less for 4 year car at the end of the lease. If Motability did move to a 4 year lease wouldn’t they expose themselves to higher cost in the 4th year, the car may well be out of manufactures guarantee. It would be interesting to see Motability’s financial models for 3 and 4 year leases, if they do have a 4 year lease model.
