It is indeed a Type III Notchback. Not as common as a Fastback or a Squareback, but a few made it into the US. I think they were more common in Canada, but I'm not 100% sure.
I don't think the notchback (not its official name, as far as I know), with 1500cc engine, was ever officially imported into the US. I don't think that happened until after the 1600cc Fastback and Squareback models were introduced.
