Rhodgie, a little harsh but true none the less. not all drivers on motability need electric seats or heated seats etc. bmw audi et al have always had a long list of optional extras that are standard on others.
even vw back in the day, i had a mk 1 golf ordered from new duty free as i was serving in germany at the time and even the radio cassette was an extra.
there are plenty of estates with far more kit as standard than the bmw if electric seats are so important or is it more important to have the badge lol.
