Thanks all. I thought as much, but always best to check.
@jojo22 It’s a private car purchase – nothing to do with Motability. There’s no question of my wife ever losing her entitlement as she is a full time wheelchair user and not even able to stand unaided, let alone walk. I suspect that there will be a light touch review at around 10 years, but that would just be an admin irritant rather than a cause of concern. I believe that one of the aims of the Timms review is that people such as my wife, whose condition will never improve but only worsen, shouldn’t need to even do that, but we shall see.
