Looks like I am pretty much priced out of Motability now. No good advance payments for a vehicle large enough for a wheelchair that is not an estate (I would never get out of one, I need something higher) with electronic handbrake and rear view camera.
Motability have offered to extend the lease (ends at the end of September) as they are unwilling to offer help towards an advance payment as my current car just about meets my needs albeit with some annoyances/mild difficulties. I think I’ll take that and then walk away.
