 We've had our Sienna now for eleven months. Very comfortable, I love the leather seats. Very spacious with great acceleration and having owned Toyotas before very confident in its future reliability. Ergonomics of the interior controls is just very good. Everything is easy to reach. I do like Toyota's infotainment strategy. The radio has knobs for tuning and volume in addition to the controls on the steering wheel. You also don't have to go through a lotta of menus to do very simple tasks, such as turning up the heat.  Also worth mentioning is the incredible turn radius this minivan has, I know, something you normally wouldn't think about. So easy to do a U-turn in very tight spots. Only two negatives I can come up with regarding this vehicle: Wind noise on the highway is bit too much even for a minivan. Second, bottom part of front bumper, is just too low. It is very easy to smash it on those concrete stops at most parking lots. I know because my wife already scrapped it a couple of times. Over all we're very happy with it though.
