I have a Cadillac 2008 SRX and it is nicer than a Lincoln Navigator!
But the Lincoln Navigator has a wayyyy smoother ride! Inside my car is really really nice! Same with the Lincoln! I would say if you're looking for a classy vehicle get the Escalde! If you're looking for a smooth nice ride get the Navigator! I am a classy upscale women and if you are aswell get the cadillac! : ]
Hope That Helped You!
If you have any more questions just ask!!!
I personally prefer the Navigator. Built very solid, looks nice, and ridiculously comfortable. It is down on power compared to the Escalade though-that's the one advantage of the Escalade. Also,both guzzle gas, but you probably already know that.
