Even if I did like the looks of it (still can't get over the rear end; I was behind one near the dealer's yesterday and it looked so Lexus bland and boring), I'd wait until a few years. Maybe when the first face-lift appears.
My granddaddy told me to never buy the first build of anything; I'll let others be the guinea pigs....
That puts me in a perfect place. Some good years living with my W211 E63, and then maybe (?)..... although by that time the competition will be beckoning me, too. 550i/M5 anybody ?
