Who knows right now, Guess you’d have to be really lucky.
I did buy a car recently and left the scheme although I’m south of the border in the midlands, almost Yorkshire and had to travel to Dudley to get it but in 4 weeks. which was better than the 5/6 month wait i was told for one on the scheme or longer on others some have been waiting a year or even 2 now for cars and some just haven’t arrived and been cancelled or users have cancelled after specs have changed. Maybe widening your search may help if you can travel to pick it up and as you say you flexable as long as it’s not small.
