The Chevy... absolutely. 1950... good. Business Coupe... good. Rotisserie restoration, assuming quality work... good. Nice shiny black paint... good. Later 235 engine, hopefully 1956 or newer with insert bearings and full pressure oiling... good. Shouldn't be too hard to find a back seat. I think some of the business Coupes had seats and some didn't for that year? I forgot for sure. I think you can put one in regardless. If you don't have more than three little ones, I think you'd all enjoy the coziness of the Business Coupe interior. And I think you personally would enjoy driving the Chevy with the smooth slightly buzzy 235 with the 3-speed column shift more than you would a fairly mundane V8 and automatic transmission. I drove a stock 1952 Chevy 2 door sedan years ago and enjoyed it. The three speed cars come with a 4:11 differential. And that's perfect for around town and parades as you said. The cars with automatic transmissions had more of a highway gear. If whoever built that car may have installed an automatic type differential... and that helps the old Chevy 6 engines to live at highway speeds. Good luck!
