this looks like a 40 plymouth, look at the speed lines on the back fenders, also the wiper's are located below the windsheild. I have the same one in my garage, just about the same shape too.
I'm pretty sure it's a 1941 Plymouth or Dodge.i'm told that was the first year for that one piece curved rear glass. I had to look for that glass for one of my 41 Plymouths and several people mentioned it.
You're in luck - It's a 1940 Deluxe Luxury Liner 4 door sedan. 84,946 of these cars were made. I remembered it from a book I own called Cars of the Fascinating 40's (by the auto editors of consumer guide.) It shows a picture of a brand new one on page 15.
I think i know what this is, I know where one is but a log skidder did it in. I believe its a 37 Lincon Zephre, My dad sold the Zephre emblems that were on the hood years ago. this car was his uncles and was left to rust. wish I had done something with it a long time ago.
It looks like a '39-'41 Plymouth to me, but it'd be nice to see a shot of the taillight area, or a better shot of the rear fenders. Maybe you could get some kid to clean up the leaves for five bucks. ;)
My father says it's too young to be a Chrysler Airflow, he says it a 39 Chrylser DeSoto or Plymouth...they all used the same body shells. Without an emblem, you can't tell.
