Another OT car advice thread - but it's a good way to hear from people who have driven these models. My wife is looking to purchase an AWD luxury SUV later this year. The choices so far are the Lexus RX350, BMW X3, Mercedes GL, or the Acura RDX, and probably nothing smaller or much bigger than these models. We don't need a 3rd row of seats. My guess is the Lexus has the softest quietest ride among them. And I guess the Acura and Lexus have 6 cylinder engines, while the German models have the 4. She has driven a Toyota Highlander in the past and fears the Lexus might be too much like a new version of the same thing - boring. She wants the interior to be luxurious and comfortable for those long car trips to Happy Valley. And she wants all the tech stuff - lane departure, adaptable cruise control, blind spot warning, back up camera, a great sound system, park assist, rain sensing wipers, but one of the main criteria is the ease of use of the NAV system. The other factors are the ease of getting two sets of golf clubs in and out without having to lower the rear seats, and she wants enough power to merge or pass with plenty of acceleration. Minor differences in price are not too important as we tend to keep our cars for at least 10 years, but reliability is. FYI, I drive a Mercedes and am partial to it, but she finds the command system somewhat confusing. What say you all knowing board?
