I have a 300E with a 5 speed, the car got hit and i stole all the interior for an interior swap in my old 300.
The engine head and alot of stuff is gone, but everything for a swap is there. Hit me up if you are interested. Im in Bellevue, and the car is in Moses Lake (eastern washington).
No idea what its worth, but i do know how rare these cars are

Also we have a 190E 2.3-16v that is about ready for sale.
