I think you may be missing the point a bit. We are talking the used car market so it would be easy to do.
I won’t go into anymore details at the moment as I think there is a valid option here particularly for people who want a smaller outlay/monthly payment, don’t do a lot of miles and are just looking for a reliable car for day to day use. I used to be in the industry years ago and have contacts that I might explore. I wouldn’t be setting something up for myself to run with due to my conditions but I have a few people who could manage such a scheme and would have backing by some big players in the different markets involved in the car industry. There are also a few glaring holes in the motability proposition that would also be addressed that would suit a large number of disabled people throughout the country.
Will keep you posted after some discussions with the relevant parties that would be involved.
