One option that many over look but is possible and may be worth a concideration..
Many believe if the scheme member doesn’t opt to purchase the vehicle is sold at Auction. In fact Auction is the last option and for the most part most are purchased before hand, order of resale: customer/supplying dealership/back office trade dealers/Auction.
my point being in some cases its possible to approach the supplying dealership who can purchse the car a lot cheaper than the customer have them service it and check it over and even add warranty if necessary and sell it back to the customer for less than purchase price given by Motability.
The Dealership makes money, the customer saves money and still ends up with their Car. Motability incur no costs moving the vehicle around the country and paying handling payments. Having the conversation with the dealership could prove prudent.
