Actually, Bill, I believe that's not 100% accurate.
Here's the best table I could find that I didn't have to remake. Doesn't show production numbers, but I think it gets the point across.
Ford clearly dominated sales through the first half of the '20s.
But most people don't realize that Chevy actually outsold Ford for two out of four of the Model A years. And that Chevy outsold Ford in 1927, 1932, and 1933, too. Ford fought back during the middle '30s, but after that Chevy took over until WWII. From 1926 to 1941, inclusive, Chevy was tops in sales nine times and Ford just seven.
One personal experience many years ago suggests those who target the wood-framed bodies that Ford largely abandoned by the mid-to-late '20s as the reason old Fords of this era have survived at a much higher rate than Chevys are on the right track.
In my later HS years, I bought a 1926 (IIRC) Chevrolet sedan that was essentially complete, out of a guy's garage near Nashville, for $80. This would had been in the very early '70s, perhaps very late '60s. Every single piece of body structural wood on the car was extremely rotten and all the nailed-on external sheet metal body panels were literally falling off.
It's been almost 55 years, thus my memory is a little fuzzy, but I think I quickly sold the car to someone else for $200, without having to actually move the car first. I think I hleped guy who bought it from me take it to his place.
To this day, it remains the most profit, percentage-wise, I ever made on a car I bought and then later resold. LOL.
