By the late 1930s, Fords use of the Model T/A/K designation had changed, and now they just made a single car, available in Standard and DeLuxe trims and designated by the model year. This next car is a 1940 Ford, which can be generalized as a 1937 Ford with a few small (year by year) cosmetic changes. Find this 1940 Ford 2-Door Sedan here on eBay bidding for $10,200 with 6 days to go, located in Woodbury, NJ.
The 1940 Ford is one of those icon and classic shapes that will never go out of style -- in fact, you can even buy an entire new body from freshly stamped sheet steel (in Coupe shape) if you find a frame sitting around...or you could buy a new frame too. The '40 Ford is one of few cars that you could probably build one from scratch with new parts, just don't expect to get any of them at your local Ford dealer.
The only option for engines in 1940 was a 60 horsepower 2.2 liter or 85 horsepower 3.6 liter Flathead V8 -- no 4-bangers or inline-6s available. This one has its flathead mated to a 3-speed manual gearbox, but with a $29k asking price, I might just go look for one that needs a new body.
