Buick, yes. I think this one is an E Series car from 1917-18 going by the headlights. It is not a closed body, it is a touring with a 'Detroit Weatherproof' top. Buick's first regular production sedan was for the 1916 D Series - sedan production in 1916 was just a few hundred out of total production of over 100,000.
I see by the licence plate that the pic was taken in 1922 .
