You lot are comparing S-Class, E-Class, C-Class with this? Let me put it in a rough perspective for you lot: its like comparing Honda NSX with Honda Legend, Honda Accord, Honda Civic... is that a sane comparison?
7-Series the daddy! right. But what if you fancy an old 8-Series and not a big hideous bath tub from today's market?
You cannot compare this to big luxury sedans. Thats the bottom line.
Are you a buyer? So?
