I'm plannig to insulate the outside wall and a half of the garage and
I'm wonderring if a vapor barrier is really needed. between the two
doors and all the opening and closing, there's plenty of air exchange
and the outside is already covered with house wrap, and I wouldn't
really get any air infiltration benefits. So I'm thinking, "What's
the point?"


Yes you should. The vapor barrier will keep any moisture away from the
insulation
