Hello, the scene is 14Mb inside there is a cardboard box, 3 tires, 1 clutch, a floor and a room with a window in it. The clutch exists in the form of a second blend file that must be unpacked by doing: files ---> external data ---> Unpack linked libraries. A new "clutch17.blend" file will be created at the foot of the clutch.blend file. Finally it is possible to study and modify this file. Good work everyone!
It's in the attic 'cause you been meaning to put it in the old beater, but never get around to it. Cool.
