So, Chevrolet is 100 years old today. GM was 100 years old in 2008, so what did they build for the first 3 years ? My guess would be GMC trucks. (That's probably why they keep the nameplate, even though they are 99% the same as a Chevy truck.) It's scary that I thought that the 50 year GM anniversary was a big deal, in '58. Maybe it's even scarier that they are still around.
