I was considering either Honda or Sienna. Test drove several of both. Sienna interior turned me off, it just seemed so plain, acceleration and handling was adequate but seemed the Honda was better at both. However both are good vans and safe. If you buy the Honda EX-L RES model, you need to replace the DVD to CD control cable for it to work properly with the wireless headphones. There is a service bulletin for this. Also you may get windshield whistle which the dealer was kind enough to replace the molding, it stopped. Other than that it's a great vehicle. Husband loves the sunroof and bright headlights. Only thing to worry about is the potential runaway problem.
Interior and Exterior design, sliding doors are solid and reliable. Acceleration and handling. Magic seats are great and tons of storage. I'd buy another Honda.
Bit of a blind spot on driver side, buy a small blind spot mirror (it works). DVD wireless headphones don't work properly unless cable is changed, there should be a formal recall on this one.
