Being an eccentric french inventor, the Marquis built in some curiosities. The car could be split in three parts. The flower-motif was printed cloth and as an accessory you could order the couture for your wife with the same cloth. Its back suspension worked with the compression of the spare wheel -without the rim of course. the obus-shaped 2cv headlight could pop up as aerodynamic feature.
it was fitted with modded 2cv engine and returned with the much more powerful Panhard engine.

The Marquis later turned up wit a small formula car with 2cv suspension, cross linked...
