Hi guys and girls. I am looking to buy a new SUV. Main concern is to have best comfortable for my family, stable road experience (Eg. Least bounce when sitting on the rear seat. I tried sit on BMW X5 the back seat jump like hell) and safety.  Personally like the Lexus RX 300 a lot. What do you guys think, is it worth it, or you have better option in this price range?

Thank you. I am noob in automobile
