Researched and test drove the Acura MDX,Toyota 4Runner and Lexus RX 350. Purchased the 2010 FWD RX350 and could not be happier with my first RX 350. At 6'3,I was worried about comfort, especially on long trips but after making two 500 miles trips, no problems. The ride was quite and very comfortable. The RX350 has more back seat room than my 2007 4Runner and everyone loves the reclining rear seats. Have averaged 19 MPG city, 22 MPH Hwy. Only complaints so far are a weak stereo system and the black/gray screen for the nav/comm control panel. Needs to have some color in it. Surprised at all the negative comments about this vehicle. So far I have very pleased at my choice at a entry level SUV.
Drive is very quite and comfortable. Keyless entry and exit. Heated and cooled seats, reclining rear seats. Satellite Radio is a great feature on long trips.
Better standard stereo system. Can't believe that body side molding is not offered as an option on the 2010. The display screen for non-navigation models needs some color in it.
