"New" 2011 Nox LT2

My wife and I just bought a 2011 Equinox LT2. 12,000 miles 7 months old. A lady traded it in for a different color. Great deal. Even trade with our 07 Tahoe. I have a quick question. The vehicle is white with the chrome package and 18'' rims. Has camera and sensors, heated seats, and sunroof. To me it looks like options were added. It really can't be told from an LTZ other than DVD and Nav. Can you get an LT2 like that or were some options added. By the way, it's a 4 cylinder. When they drove it up I swore it was a V-6 because of the rims- until I popped the hood. We are excited about our "new" vehicle. I have an 08 G8 GT and I love it! I think I might just like this Nox better than the Tahoe Tank! We pick it up Saturday.
