Here is footage from the East Liberty Ohio Honda manufacturing plant in the late 1990s, maybe 2000. You see parts of the process of assembling a 6th Gen Civic sedan (LX or DX). Video identifies manufacturing process features that the videographers seemed to think significant for some reason: stamping the front fenders, laser welding, painting, door install, wheel install, and other topics. Much of it automated, much of it still manual labor.
Looks like there is an Acura on the line in some shots, too.
