There are / were no £40k+ cars available on Motability

Can't find it now but there's a breakdown of the cars supplied somewhere and even when small BMWs etc were available very few people chose them - most people chose smaller average cars

Motability also plays a huge role in priming the used car market in the UK - without them there would be less choice and cars would be more expensive

> There are / were no £40k+ cars available on Motability

This is categorically false.

> Motability also plays a huge role in priming the used car market in the UK

You could also argue that it's distorting the market. Having billions worth of subsidies supporting a market isn't necessarily good.
