Mitt Romney has had issues in this campaign with cars.
You may remember his "two Cadillacs" comment in February, immediately characterized as a gaffe for a candidate who has often seemed to struggle with how to address his wealth on the trail.
"I like the fact that most of the cars I see are Detroit-made automobiles," said Romney in Michigan. "I drive a Mustang and a Chevy pickup truck. Ann [his wife] drives a couple of Cadillacs, actually."
