No mate, that E55 i went to look at wasnt as nice as it looked in the pictures, and wasnt really as described either. The engine didnt look good, although ran smooth, and the "rebuilt" trans was leaking from the common areas they all leak from before they are repaired.
It also failed a roadworthy inspection, the interior was poorly presented, and it wasnt worth the $18,000 he was asking. The car is still for sale too.
