Yes, definitely different sides to the issue. I imagine they may be less appealing to the dealers but more appealing to the customers, although, the price of a car usually drops in the first 1-2 years, so might not be as bad for 5 years. Still, pros and cons as you say, you would think a car would be cheaper to Motability if was leased for a longer period of time and from my understanding any adjustments are removed from the vehicle to remove it to normal before it goes back to the dealer, so all those extras, adaptations and modifications that people had to make to their car are lost and have to be redone on their next car, so it is quite understandable someone wanting to save themselves some money, not have to pay to have this done again, they might have gotten used to the car and may have done low mileage etc, on it. Many things to consider.
