I really like my 2006 Cadillac Escalade EXT a lot more than I did my 2003 Cadillac Excalade EXT. I drove the 2003 for two and a half years, before trading it for my 2006. The 2006's ride is a lot smoother, and is more comfortable. I drive from Georgia to Florida a least once a month, so the comfort and room that the EXT provides definately suits my needs. When I am at home, I use the EXT around our farm to carry feed and hay, it is a workhorse also.
The navagation system and the XM radio are my two favorite features. I also like the larger tires and chrome wheels. The electric top on the back is pretty neat too.
The one improvement I would like to see is in the engine. I wish that Cadillac could come up with a Northstar engine that could work with a larger vehicle, instead of the engine they now use.
