2017 Toyota Sienna Minivan SE Premium 8-Passenger 4dr Minivan (3.5L 6cyl 8A)
Greatly Improved over 2014 Sienna
 I totaled my Sienna 2014 XLE after 3.5 years of driving it. I hit two deer in a 75 mph zone. Air bags deployed, and I wasn't injured except for ear problems due to the side airbag hitting me in the ear. I now have a 2017 Sienna SE Premium.  Technology is much advanced since 2014. The BlueTooth interface is greatly improved (much easier to use with a shorter introduction: "How may I help you" as compared to the long explanation before), though during phone calls people can still tell I am in the car (however, one friend told me it sounded better than the 2014) .  By comparison, with my 2010 Kia Sorento BlueTooth, people usually couldn't tell I was driving. The Kia had the microphone on the driver's side windshield pillar; Toyota has kept the microphone in the center above the rear view mirror. iPod interface is greatly improved since 2014. The navigation screen is bigger and better.  There is now an information screen in between the speedometer and tachometer. You can customize the screen (mpg, digital speedometer, miles to empty, etc., outside temp is always displayed on the screen) as well as view turn directions, speed limit, and iPod content from the screen.  The seats are much more comfortable than those in the 2014. Down hill assist works great: I do a lot of mountain and hill driving. The 2014 had down hill assist, but it didn't work well. Cabin lights are improved: window, door and cup holder lights are brighter and easier to see; they are now blue instead of green.  The ride seems quieter than the 2014, even though the SE comes with 19" rims.  The handling is better--tighter, more responsive steering. The engine is now 8 speeds for better gas mileage, but I notice that the pick-up isn't as good:  it seems to take longer when I step on the gas getting onto the freeway. The 2017 comes with LED daytime running lights, and the tail lights are LED, so that it looks like they are all white until the diodes light up. The SE does not have automatic third row windows--I miss that: they can only be opened manually.  The XLE comes with automatic third row windows. The SE Premium comes with 6 speakers instead of four, which is one reasons I went with Premium; however, it also has a rear entertainment system, which I think is a waste. I didn't want it. I would have preferred automatic third row windows or parking assist or adaptive (radar) cruise control, or a subwoofer, or another moon roof, or cooled seats to a drop-down screen that sometimes rattles and will probably never be used.  All that wiring for nothing (Blu-ray player to screen, input jacks in the rear (s video?!), headphone jacks, wired into the sound system)! The built-in Blu-ray player takes the place of a storage shelf that I used to use.  I almost backed out of the sale because I didn't want the entertainment system. Why oh why, Toyota, did you have to put the entertainment system in?  People have iPads and gaming devices with better screens, but I can't buy a stand alone cooled seat, or automatic third row windows, or any of the other useful items I mentioned previously which would have taken much less wiring. What were you thinking? I went for the SE instead of the XLE because I wanted a black interior. I wear a lot of dark clothing and had problems with dye transfer in my 2014 Sienna with its light grey seats. There are still two glove compartments, but the top one no longer has shelves and seems smaller than the one in the 2014.  There is a feature that uses the front microphone to project the driver's voice through the speakers so people in the back can hear the driver better. Interesting. We used it just for the fun of testing it out. It works, but is it useful?  The dealer threw in rear parking sensors for free as I was waivering.
