Interesting video on 6.9 values. And I think Pierre is right, Mercedes making so many parts NLA is what is causing the value of these cars to lag other classics. People are scared off them.
Dear old Bills car is currently at an auction house. With only 2 days left, bidding is at a paltry $22500. It was advertised a few years ago over $100k, with obviously no takers. The market is very strange; they SHOULD be holding values around that price but sadly they are not. Not helped by saying it’s an AMG & not purely stating original AMG upgrades included.
