Important details to include:
Original radio?
Full door panels, not cut for stereo speakers, that have both the front open map pockets and the NLA fold-out map pockets under the door arm rest?
Headrest seats mean standard seats? Condition?
Tool kit?
Original color? When was it resprayed?
Since it's an E and left the factory with the horrid soft "Comfort" suspension, when was that replaced? And with what kind of shocks?
Sway bars?
Stock H1 headlights?
Original steel front bumper or after-market FG front splitter?
Any funky extras? thermometer for exterior air temp? Rear window wiper?
All these things and more can be the difference between lucky to get $15,000 or fielding multiple offers for over $30,000.
Good luck.
