Not to spoil anything but right now the Duesenberg SJ Bauer is second on the list at 20 feet and 6in. This. List. Is. Taking. Forever. The problem is companies like Cadillac created the Series 60, Deville, and Eldorado. Called them different cars but they had the same body and same length same goes for Chrysler with the Newport/300/New Yorker and so on. So I am chasing cars down rabbit holes endlessly coming to the same result. I should be down soon though I just wanted to vent a little. And the pre war cars always vary in size thanks to coach builders so lengths of pre war cars are next to impossible to find.
