I traded my 2000 Lexus RX 300 for an '06 Escalade EXT. Although I considered staying with the Lexus family, I felt that the RX 330 and GX 470 SUV's were way too small and did not offer enough features for the asking price. In the Escalade EXT, I get a bigger, sturdier vehicle, with the same luxuries (if not more), and it's so much fun to drive.
OnStar, XM satellite radio, heated seats, overall roominess, cargo space, body style... the list goes on and on.
The glove box and center console could be larger. I don't like the drop down DVD monitor in the rear... it blocks my vision in the rear view mirror. Add heated seats to the second row.
