I just heard Laura Bush at rally in Florida say that back in '78, when George was campaigning for senate in Texas, they used to drive around in a "Chevy Cutlass". It may not have necessarily been a '78, more likely a '73-'77. From what she said, all I could tell is that it was a GM product. Anyhow, the Bushes have worked their way up the GM ladder and are now in Cadillacs.
