Vintage Cars: 1940 Chevrolet sedan, classic chevrolet, war cars

Question
How can we research the history of our 1940 Chevrolet Special Deluxe car? The VIN# is N5510.

Answer
You need to search the web for sites like "classic Chevrolet forums" or something similar.  A site with a forum, where you can ask this question of fellow classic Chevrolet owners, will be of the most help.  With Chevrolets, you'll find a wide variety of sites, like some for pre-war cars like yours, others for 1955-1957 models, etc...
