In order to extend the lease to 5 years the vehicle has to have substantial modifications or have less than 20,000 miles otherwise they only allow a 6 month extension.
Having said that there are folks on here who have not met that criteria and after speaking to Mota have been able to secure a 2 year extension based on their specific circumstances but it’s by no means guaranteed!
As for getting a purchase price, that will not be happening as Motability have changed their policy and no longer allow scheme members to purchase their vehicle at any point.
