You may not get hot and bothered about horsepower, tiptronic transmissions or cornering ability. But stroll through the mammoth Houston Auto Show, and you're likely to become an expert. This year's event features a slew of rides, including the 2007 Ford Shelby GT500 (and its ridiculous 475 horses) and the 2006 Lamborghini Gallardo Spyder. Yuppie types can check out the 2006 Audi Q7, the automaker's first SUV. Consider this your chance to car-shop without being assaulted by the guy in the bad suit. Noon to 9:30 p.m. today. Show runs through February 5. For tickets and a full schedule, call 832-667-1400 or visit www.houstonautoshow.com. $10; free for children 12 and under (when accompanied by adult).
