#305 ALART - Alart Coupe, a little French sportscar from 1959. Saw one in the Cite de l'Automobile museum in Mulhouse a couple years back.
#10600 MORETTE - is it a company that manufactures bodykits for cars, mainly dealing with headlamps? Doesn't sound enough to be in your list to me actually, but who knows. They have originated in France, but later seemingly moved elsewhere.
#11303 ONE SIX TWO - I'll use a time range hint here.
#12062 PONTIAC - pretty obviously, an American manufacturer established in 1926, part of GM.
#15051 TONGBAO - Suzuki-based small commercial vehicles. Sounds like they must be Chinese, but all of the sales ads I've seen were from Uruguay for some reason.
