We are very happy with our new Suburban LTZ. We were able to get one of the last 2010 models. So far, everything is great. Impressed with the NAV, particularly compared to our Acura MDX. OnStar is also impressive, but a bit expensive once the free trial is up. Very smooth ride, quiet, and a great sound system. Sufficient power and the cylinder management really seems to help with gas mileage. It is a big car, so it takes time to get used to the braking. We now have plenty of room for the kids and dog.
