Oddly, this car is actually not a Lincoln Continental. Perhaps developer's oversight led to the mis-naming of the vehicle. Lincoln Continentals of the forties all had what was known as a "Continental Kit", which was a spare tire mounted on the rear of the car. This is what gave it the 'Continental' look and was inspired by early European sports cars that said invented the practice due to their lack of storage space.
In L.A. Noire, this car is actually a simple '46 Lincoln Convertible, the successor to the Lincoln Zephyr of that model year.
