I agree with Chrisk – if you’re the one using your Motab vehicle then you would know how you treated the car.
In my case, I would buy back my Motab vehicle as I know how I’ve treated it and the fact that it’s been serviced every year.
The faq link given by above poster has been there for some time and I’m assuming you can’t but it back after the lease period is complete as I contacted my dealer a few days ago and he told me that the best way is two weeks before exchanging for new one or returning existing vehicle, just ring Motab operations and ask for a purchase price and it would be less than the dealership price.
