The interior was in great shape when I bought the truck so that has made it fairly easy on me as far as upgrading it goes.
This is a pic of the interior the day that I went to look at the truck.
These are some pics of the interior as it is now.
I had the trim colormatch and I installed a set of escalade gauges out of a 2000. While I was at it I went ahead and installed blue leds in the gauge cluster, hvac control, headlight switch, and 4wheel drive shifter. I installed cool white leds in all of the courtesy lights. 
Heres some pics with the leds. 
I really like the escalade gauges and the blue leds.
