I'm thinking about buying a new (or slightly used) w140 Merc. I'm only interested in the V8's and V12's for a car this size. I'm not opposed to checking out the coupes either. Is there anything specific I should avoid or look for?
Also, in the case of a new car that the factory couldn't sell, what kind of price reduction should I be asking for? I understand that the new S-Class is a whole lot cheaper than the 140's were during their hey day...
