 The Sequoia has been great!  It was bigger than I thought however drove much smaller very nimble.  I did not like how the Tahoe and the GMC products steering felt (too loose), and the entrance to the back seats are much easier than the Navigator.  The engine sounds deep when you step, otherwise fairly quiet.  Gas mileage is not good but it's a V8.  No problems with squeaks or rattles of any kind.
