Charities are very much about ethics and morals. With regards diesel cars – they are Dinosaurs and I think that many manufacturers will dump these types of engines on Motability and Motability will willingly accept them – which I do not think that they should due to the greater environmental concerns that we are now facing, in fact I would say that Motability should have a policy of scrapping all diesel cars on the scheme within 2 years – probably another unpopular opinion 🙂
