I still have my registered auto business and I used to buy direct ex mota vehicles, probably still could but not been trading regularly over the past few years as now fully retired (well almost). They were certainly a lot cheaper than the price they ask from mota customers.
Interesting and confirms what many of us have said for years, that the prices quoted to Motability customers to buy at the end of lease are set deliberately high as a disincentive to those considering opting out of the scheme. Given the profit that they make out of every lease, you can see why!
