Stop in for a cup of coffee

How would you tell the drivetrain is low miles. I pulled the breather and from what I can tell no sludge at all. All the boxes/relays are factory though. Really makes a price difference selling it.

I would think if you pulled the valve cover off the engine, the trans pan from the trans, and the inspection plate from the rear axle (7 1/4" I would think), that it should be very clean inside and you shouldn't see very much wear on the gears etc....
