1940 Mercury 09A 4-Door Convertible

This 1940 Mercury 09A 4-Door Convertible is an exceptionally rare piece of pre-war American automotive history. Mercury built this body style for just one year, with only 879 examples produced, and it is believed that only 24 remain on the road today. Starting with a 100% solid, rust-free West Coast body, this Mercury received a ground-up restoration to a better-than-new standard with tasteful upgrades throughout. Finished in show-quality, hand-rubbed lacquer in its original Garnet Maroon, it is an investment-grade collector car with standout presentation and performance.
