A test drive will only provide you with a limited amount of time with the car. As one then owns the car, discoveries on features, details, and experiences surface. Post your discoveries that surprised you in this thread, the great or not so great ones. I will kick it off with the fabric-based wind deflector I was pleasantly surprised to see since not even my current RX has it. Very nice detail! Of course, not to mention the power sunshade, again not in any Lexus/Audi I've owned.
