Motability are by far the largest leasing company in the UK, I believe.
Therefore they should be able to negotiate the best discounts in the market. This must be passed on to lower APs.
Plus have a big say as to what a Motability vehicle should have fitted as standard. Such as rear camera, front rear parking sensors, tyres that work in the winter as well as the summer. Michelin cross climate for example. Full size spare wheel/tyre. SOS button so driver can summon help.
If not fitted as standard then have them listed as a no cost option, like metallic paint is now.
“Motability” is a charity and should not make a profit, yet it has £2.4 billion cash stockpile and pays its boss £1.7 million a year.
