Resource for 1941 Buick Trim/Model Specifications? in Buick - Pre War Posted October 23, 2019 · Edited October 23, 2019 by Sharps45-70 (see edit history) 7 minutes ago, neil morse said: My Super has the optional 3.9 rear end, so what Matt says about its cruising speed is accurate. I routinely drive it at 60 mph. I have had it up to 65, but I prefer to drive at around 55 to 60, where it seems very comfortable. Good luck with your search -- Buicks are great cars, no question. Neil Thanks for the information everyone. I know I want something prewar. While my ultimate goal is an early 30's full classic, the funds won't be there for a while, and realistically it won't be as reliable or capable as a driver as an early 40's car. Really, my main debate right now it whether I want a 1941 Buick or a 1939-1941 Cadillac (60 special or 62). I like the uniqueness of the inline 8, and the extra power, though I know the Cadillac's are excellent cars for long distance cruising. Such a hard choice with no real wrong way to go!
