Kezo, I think you are over thinking this millage thing. I merely said it was a factor, like if someone adds a panoramic roof and leather seats, that car is going to fetch a higher price, so why should Motability Operations be the only one to benefit and I think we can acknowledge that they benefit big style to the tune of over One Million a year.
There is absolutely no additional paper work by any dealer, (or any calculation of milage) as all I am talking about is the final price and what that extra profit was and the only extra work is by Motability giving a percentage back to the customer of excessive profiteering. I am quite sure Motability Operations is able to cope with the very slight extra paperwork, they have the Billions to higher a few extra staff.
At the end of the day no one needs to be able to put their finger on why the car made x profit over the book price, they will only need to know it did, as there could be many factors and we know that at present Motability Operations are the only one to financially benefit from it.
