You're right, John Mellencamp, this is our country. Just make sure you're including all of North America in that grouping. The Chevy Silverado and its doppelganger, the GMC Sierra, have all the makings of a big, durable, contractor-friendly, all-American truck. It's just that last adjective that General Motors ( GM) still has a bit of trouble with. Sure, some of the trucks are assembled at plants in Flint, Mich., and Fort Wayne, Ind., but a sizable number are also made in Silao, Mexico. Even those made north of the border aren't quite "American." Auto pricing site Cars.com booted the Silverado and Sierra out of the Top 10 of its American-Made Index after its pieces slipped below the list's cutoff of 75% domestically produced content to only 61%. That's no knock on the Silverado's quality, just a reminder that it takes a global village to raise a Chevy pickup.
