With the tank destroyer motto of “Seek, Strike, Destroy!” in mind, Buick was tasked with building the Army a prototype. Its design studio, under the tutelage of legendary automotive designer Harley Earl, went to work in the fall of 1941, mounting a closed turret with a 57mm gun onto the chassis of a light tank.
Nice but how about those Chrysler tanks?
Great gift idea for any of your liberal friends.
