Same boat as me Mike11.
You will automatically have your current lease extended by 6-months and this includes insurance cover of course. You can still go ahead and order/take delivery of a new car at any time during those extra 6-months.
I have test driven my next car but not ordered it yet. My current lease runs out on March 4th. As I understand it, Motability will automatically extend it by 6 months – but I’m not sure whether or not I have to personally inform them via phone. I guess a quick phone call to them wouldn’t do any harm and would be good manners.
