This car seems to have more than one identity. It is clearly based on the Isuzu 117, but I don't think it was badged as such. On the pictures I have It is solely listed as an Isuzu Sport Wagon on the motor show number plate, and is badged as an Isuzu Sports Wagon, so the answer would seem to be a variation on this theme, with perhaps, 117, Bellett or Florian inserted somewhere.
