Some interesting points – personally I wouldn’t want a Chinese car on principle.
The great thing about Motability is – if you have a problem they always, in my experience, do their best to sort it out.
I have had a car stolen from my drive, they replaced it within a day – I had someone run it to the back of a car whilst parked – again – provided a replacement whilst it was being repaired.
Motability takes all the concern or worry out of a purchase at what I consider to be a very fair price – so my concern would be if they ever went bust!!
