The one specced in the road test was £90K.
£75K for the "base model" then you add £2,450 for a LSD. Why is that even an option? You're paying £75K for a 500hp estate car and you might want a LSD.
Sure things like funky leather, super stereos, moving floors, glass roofs, disco lights and what have you, they make sense as options as it's personal taste, but a limited slip diff? That should be part of the AMG experience.
