An attractive Weymann(?) bodied roadster, or is everything behind the hood shiny alloy? Also French? You may say so... The hubcaps may help. The placement of the Tecalemit (?) grease point as well. The radiator profile does ring a bell (Amilcar C8?) but there's really very little to go on. Unless you know of course.
Update: Raould Thybaut seems quite confident about this car being an Excelsior , see his comment and check another Excelsior he is showing us.
