Bonne Année! And a 1949 Oldsmobile.

Michael Moore spotted this lineup at Orval's Used Cars in Delta Colorado. I think that's an Olds lurking, third car in. Second car a Mercury? First car looks 1946ish to me, but I can't say what make. Help, please. I'm looking back over the 2016 posts and trying to choose an Autoliterate Truck of the Year. Suggestions welcome. The Chevy Panel Stephen Hendrickson spotted in Brooklyn a few weeks back is a strong contendah.
p.s. The first car is a 1941 Buick. Thanks to Larry Nordell..."Thanks to my uncle John Eliot Spofford in Boston, the first one can be identified as a 1941 Buick"
And Mr Spofford suggests the second car is no Merc, but a modified version of the Buick.
