when i was at the Toyota dealership a few weeks ago, i noticed a "accessibility version" of the Sienna there...not sure about the details, but they might be the only one who make one (rather than a separate company)?
i sent my friend the link, and is interested in it, and he plans to go the NAIAS to see if he can get more details of what is available...one thing he wasn't overly impressed with is the 4.6L V8 with 240HP, when Chrysler's Pentastar V6 is 283HP...i admit, he has a point...the 4.6L isn't even used any more (it's last use was the Crown Victoria, i believe), so one would think a more modern power plant might have been a better choice.
