This is how ill thought out it is,a self employed van driver is expected to change to a newer or new van,the old one could be scrap value.
Taxis,are they commercial even the cars? while identical car is OK.
Most are less than 6 yrs old,so I'm missing the point.
Plus,many small vans or campers like VW T 5s are daily drivers for some,who also will pay.
