I am a satisfied Lexus ES330 owner. I am now in the market for a second Lexus. It would be used for winter driving in the Northeast and summer vacationing near the beach. I have looked at the GX450 and know that it would serve my purposes but I like the styling and performance of the RX350. I would be taking the car on the sand (probably 6 times a year). Can the RX350 withstand that type of driving?
