I’m not 100% sure myself. It cropped up the other week that you add as many extras as you want but can’t add a pack?
Its hard to find the true answer as Mercedes UK don’t produce a Motability price guide on its website it’s down to individual dealerships, so it’s hard to know unless they state the full description and pack included (if any).
but the link to sytner group in my above post is a good website for many makes.
i think the A class looks more like the A mini E or even S class
a link to the Xi that may help.
