What year will be the start for the 4th generation? Will it be soon or in about 10 yrs? I think it will be an oddball amount of years for the 3rd to finish and start the 4th
I've been in a new 2011 Sienna, and quite a number of 2010 and 2009 Siennas. The 2011 is a WORLD CLASS MINIVAN. It's clearly the industry leader and all other minivans are playing catch-up. There is a reason that GM quit making minivans and went only to crossovers (which are very similar except for the doors and the seating is a little different) ... the Sienna was cleaning up.
