As two people correctly guessed the mystery car was a Peugeot 204 sedan:

They were built from 1965 to 1976 in sedan, convertible, coupe and station wagon form. While maybe a bit bland on the outside they were interesting cars inside: all variants had a transversally mounted four cylinder engine (gas or diesel) varying in size and were front wheel drive. Peugeot achieved that by placing the manual transmission under the engine block and the two share the same oil.
Below are some photos from a junkyard in the Vaucluse department of France. Due to the rain I wasn’t able to take as many as I wanted but I did manage to find an exhaust I need so I’ll go back on a sunny day to fetch the exhaust and take some more pictures.

The junkyard (which is actually half a junkyard, half a guy’s collection) also had other cars that we’ve already covered in these pages, including a Fiat 500:
Fiat 850 Coupe:





>SAAB never made a car where the gearbox and engine share the same oil. The original 900 does spec the same grade of oil for both, but they do not share it. The engine is on top of the gearbox, but the gearbox has a "roof." The original Morris Mini did, however, share engine and gearbox oil. NOT the 900.

Where are you located? if you’re in the south of France, I might be able to find you one.
