My wife and I looked at these two vehicles when deciding to purchase a mini van. Others in the market did not have the build, drive, and quality of these two manufacturers. Comparing the odyssey touring edition without pax tires (do not recommend pax tires) vs. the sienna limited edition here are the pros and cons of each: Odyssey: Pros: Front load dvd player, good storage, middle seat in second row, better layout of buttons for opening side doors, power rear lift button (not a strap that needs to be pulled) Cons: Seats are not very comfortable, brakes not as responsive and strong, fuel economy
Sienna: Pros: Strong/responsive brakes, comfortable seats, navigation screen appears sharper, stronger engine with more pickup, dynamic laser cruise control Cons: awkward location of switches, back load dvd player, no middle seat in second row (a must with little children, fuel economy
Both vans had a impressive ride with the Honda edging out the sienna for responsiveness. Cabin noise similar. Hard to find a sienna van with the features you want (frustrating shopping experience). Honda makes it easy. I could provide more details but the site limits input. Hopefully this helps!
