"Not to her great credit, U.S. Sen. Dianne Feinstein owns a gas-guzzling SUV, even though she believes in global warming and doesn't want to drill in Alaska's Arctic National Wildlife Refuge. In fact, last year the Los Angeles Times reported that she owned three SUVs. Which makes her your perfect 'SUV Democrat.'"
Debra J. Saunders, "Close SUV Loophole," The San Francisco Chronicle, May 10, 2001
The phrase
sport utility vehicle (SUV) entered the language in the 1970s, although in its earliest incarnations it most often shows up as
sports utility vehicle (as well as
sports-utility vehicle and
sports/utility vehicle):

"Four-wheel drive is increasingly popular. A decade ago, about the only U.S.-made '4 by 4's,' as the industry calls them, were Jeeps and International Harvester's Scouts. Today every truck manufacturer offers four-wheel drive not only on sports utility vehicles but also on pickups where it is a more and more common option and suburbans as well."

The abbreviation
SUV didn't get a toe-hold in the lexicon until about 10 years later:

"Ford, meanwhile, is planning to freshen up or completely redesign all of its light-truck recreational vehicle products in the early 1990s, in part to take full advantage of expected demand in the SUV segment of the market."
