I would assume they have records from previous services, so if someone gave a very high mileage from the last service that might raise alarm bells. I would, rather nievly, hope that customers would give an accurate reading as required. I got a pretty good price quoted to me last month for our xc60 but decided to stay in the scheme and will pick up our xc40 next week.
Interesting that you had a good price Brydo, as I always ask out of interest at the end of each lease and the prices I have been quoted haven’t been competitive at all. I could always do much better in the market myself, especially considering that the prices quoted by Motability are non-negotiable whereas you can always strike a good deal of advertised prices at a dealer. I’ve always thought it was an odd approach, as they incur auction fees by having the vehicle returned, but my only conclusion is that, given the amount of profit that Motability Operations makes out of every lease, it is in their interest to keep as many people in the scheme as possible.
