Find used cars in Houston with CarsDirect. The southern city of Houston is the fourth largest city in the U.S., the biggest urban center in Texas. Over 2 million people live within the city, with more than five-and-a-half million in the surrounding Houston–Sugar Land–Baytown metropolitan area. The city of Houston enjoys a broad industrial base, but it's also a port city, and a lot of business goes on around the docks of this metropolis in international waterborne tonnage. Among its many attractions, Houston is home to the Rockets (NBA), the Texans (NFL) and the Astros (MLB), making it a hot spot for visitors from around the state and beyond. All of that adds up to a lot of vehicle traffic. But what about the transportation Houston residents use to get around every day? To start with, the Houston area, as well as the rest of Texas, gets plenty hot in the summer; as a "humid subtropical" region, Houston temps can get up over 90 degrees Fahrenheit and stay there. That means hardier vehicles may be necessary, and those with finicky coolant systems might not fare well. Occasional tornadoes and other storms may also be hard on local vehicles. However, Houston winters are kinder to cars and trucks, and some models can last longer in Houston than they would in, say, Northern Maine. For more on exactly what kinds of vehicles are available in Houston, and what shape they're in, try CarsDirect; this site will help you find the next ride you need to get around this Texas mega-city.
