The fork crown and bottom bracket lugs make it a lower-than-top-tier model, certainly. The webbed large chainring argues for late 70s, but windowed lug looks later; the slant-parallelogram rear dérailleur ditto, especially with the black pivot plates, though that could have been replaced. Those stripes on the lower down tube and seat tube were a definite period thing with Motobécanes. I would check out Moto catalogs from some online source, and you'll probably find that bike in one of them.
