Just took delivery of my 2013 GMC Sierra-SLT,5.3L,4WD. Awesome ride, quality and fit .Just returned from 300 mile trip and averaged 20.1 MPG. I also purchased a 2013 Malibu for the wife(Christmas present and 50th anniversary gift) Very impressed with it. Base model comes well equipped. Wife very happy, loves the car and me! I will do it again for our 100th. Bowties for all!!
