I sometimes wonder about those things too.
But by now I have determined, that most Mercedes owners don't know much about their own cars.
Now , when it comes to the average flipper, you can bet they know zero.
Case in point is: does this person really NOT know, that he does NOT have leather seats in this car, let alone figure out that 40+ year old leather seats would NOT look like that ??
I would think, that it's deliberate false information !
The interior definitively has seen some serious alterations over time.
The wood is not from this car.
The seats (MBTex) are not matching to the door panels (Leather).
He found equally color coded seats and panels and threw them in this car.
I would love to see his Data card and ANY documentation , even proof about the mileage.
Who knows ? (What else was done over the last 40 years ??)
Besides the odometer being easily changed, who's to say if this has not gone around once if not twice !
Give me a break.
Naive seller looking for more naive buyer !
