I too had a email offering an extension just after the MOT (less than 5000 miles total)
”We’re inviting a small number of selected customers to apply for a lease extension on your current Motability Scheme vehicle.”
They then rang me yesterday desperately trying to persuade me extend now, even if I go on to order a new vehicle before current lease ends in March. They were very keen so must be profitable for them on very low mileage cars.
