Today at work I did a PDI on a Fully loaded 2007 Yukon XL...its nice...its got the 6 liter, navigation, woodgrain, XM Radio, fully automatic lift-gate, a turning radius that would make a lotus nervous, and accelleration that seemed like it gained a lot more than 15hp. I don't like what they did with the window switches or the front end...but the interior seems almost German (like a BMW or Benz). Very nice truck though. All for the low low price of $45,xxx
