Just purchased the 2009 Pebble Beach edition. Very reliable vehicle. The navigation system is easy to use and access while driving (all touch screen). Very powerful car, good acceleration. The backup camera is a nice feature, but the images appear farther than it actually is. Have no problem driving in sleet/snow/ice thus far.
The AWD is a nice feature if you live in portions of the country, where the winter gets bad. The bluetooth is also a nice feature, allowing you to communicate hands free. The 6 disc changer is also nice. The exterior design gives a nice sporty look, while the interior makes it feel luxurious
Was disappointed with the sound system. The Mark Levinson sound system is very average, at best. Fuel economy could be better. The braking system is not as strong as it needs to be. The RX AWD is a compact heavy SUV, and often times, you have to step all the way down on the brakes hard to stop.
