For me it strictly came down to the AWD option - the Toyota Sienna offers it, the Honda Odyssey and other minivan brands do not. The Sienna is the only AWD minivan available. While I understand AWD may not be a necessity around here and we'll likely be driving most of the time without it, the few times we'll need it will definitely give us a peace of mind. One of my good friends - a recent Honda Odyssey owner - was really trying to sway me over to the other side touting the better gas mileage I would get going with an Odyssey FWD instead of the Sienna AWD. The 2 mpg difference wasn't a deal breaker for me. Also, I was impressed that the Sienna has the ability to automatically go into AWD mode and turn itself off when AWD is not needed - further enabling better gas mileage. So in essence, I won't be driving in AWD mode the majority of the time anyway. I would say my biggest concern may be the no-flat tires that come on the AWD model of the Sienna, since they will definitely not be cheap to replace! Part of me wonders if when the times comes to replace the tires, to replace them with regular tires and throwing a spare tire in the back (knowing it'll take away some cargo space). Not sure if we'll ever go this route or not. However, another part of me wonders if the no-flat tires might be more appealing since I'll never have to go out and change a flat tire on my own
Overall, I probably prefer the sportier look to the Honda Odyssey and probably would have gone with an Odyssey IF it had the AWD option. I know it has a lot more bells and whistles that come standard to the vehicle for a better price than the Sienna too. A definite plus. My husband is a big Toyota fan so he tends to gravitate more towards Toyotas in general. He definitely veered more towards the Toyota merely because it's a Toyota. However, he would've been amenable to a Honda if I really wanted one (since I'm the one that will be driving it most of the time). For me, it basically came down to my top priorities for the next vehicle more than any of the bells and whistles, and yes, even style. Ever since having my Mustang that drives absolutely terrible in the snow, I vowed my next vehicle must have 4 wheel drive or AWD. Must hold at least 6 people comfortably, have decent cargo space, and be reliable. Electronics really aren't a big deal to us and really even car resell value doesn't matter too much to us either since we plan to have this vehicle until it basically dies. However, reliable cars tend to have better resell values in general, which Toyota tops the lists in that dept.
I must admit I was a little shocked at the bareness of the 2014 LE Toyota Sienna AWD model when I first peeked in. I had a hunch that if I looked into the equivalent 2014 Honda Odyssey model that I might've been won over in the respect. However, after test driving the LE Sienna, I was truly impressed. As I mentioned, the electronics weren't as important to us and I had to remind myself that if we wanted the whole shebang, we had the option to spend a lot more money for the extra bells and whistles. However, we really don't need all of that and really got all that we wanted and needed with the LE Sienna AWD. We get our brand new 2014 LE Toyota Sienna AWD in just a few days - can't wait!
