Upgraded from an 05 RX. The power, performance, suspension and roominess are all upgrades. The 2010 is also quieter. All electronics are significant upgrades--particularly Nav and Voice. Other notable improvements are the center console, larger interior and lack of wheel wells intruding into the cargo area. The suspension is much improved. Overall, very happy with the new Lexus. I compared against MDX, SRX, Q5 and MB. In the end, quality, reliability and Lexus service made this car the clear winner for me.
Nav, suspension, voice recognition, interior space, fit and finish. Very comfortable ride.
No storage for Tonneau, they seemed to have moved auto recirculation to the Luxury package. Leather trim seems to be slightly lower quality than earlier models.
