Test drive a unit with Autoride and one without to see if that is something you want to have. Tahoe can only get Autoride on the LTZ models (standard), it is not available on the mid level LT. You can get Autoride on Yukon SLT and it is standard on the Denali. That was one difference I noticed when sorting through the option availability. They call the standard suspension "premium", but after driving an older model with Autoride I could tell a difference.
