My 1949 Studebaker R-Series half-ton pickup. It's got a Chevrolet 350 engine in it; the top's been chopped, the front suspension's out of a Camaro, and it's got Cadillac taillights and Buick door handles. I bought it in 1989; a custom car shop out my way had dragged the shell out of a farmer's field in North Dakota and was building it as a shop truck. I bought it while it was in pieces scattered around the shop, and they finished building it to fit me.
Secretly, every woman wants an antique tractor, and this one's mine. It's a 1950 International Farmall Cub. I bought it from a farmer in 2001 in somewhat rougher shape than you see here. It earns its keep plowing snow and doing garden chores. It's actually a relatively rare "white demonstrator" -- in 1950, International took an unspecified number of tractors, painted them white, sent them to dealers to demonstrate all the new features, and then repainted them red and sold them. It doesn't really raise its value much, but it's got all the options that you could add that year, such as lights, sprung seat, PTO, wheel weights and hydraulics.
"Lucille" is my 1947 Cadillac Series 61 Sedanette. I bought this car in Toronto in 1983. It was all original at the time and carried Cadillac's flathead V8 with a three-speed manual transmission. I drove it that way for years, but finally got tired of the manual steering, and while the flathead was still strong, the peripherals were starting to give me headaches. It still looks original, but has a 350 Chevrolet engine, automatic transmission and Nova front suspension. I have no way of knowing for sure, but several clues seem to point to this car being originally purchased new by J. Gordon Thompson, the founder of gasoline company Supertest.
