That's where my 66 Chevy was built. This is one of the rare buildings still standing (on Van Slyke Rd.) in Flint. The first Corvette (1953) was assembled here. The last Chevy passenger car built in flint at this location was June 24, 1970. It was a Monte Carlo. In the early eighties Buick built the full size Impala & Caprice for one year, along side the Buicks. Here's the link to my Chevy www.myspace.com/gerrygodin.
