Looks like the 09 or 10 are good. Thanks!

 

2004-2006 share the 3.3L engine. It's a great engine.

2007-2008 had some issues with VVT-i actuators(?), and oil cooler hoses. The latter are addressable issues. The former isn't that common.

2009-2010 are the best years. But, don't hesitate from the other years either if you can get them at the right price, there's nothing wrong with them.

 

Thanks again, Jiantao.
I like the 2005-06 models, but I'm hesitant since they have timing belts. I changed one on a older Sienna once, but didn't think that it was much fun.

 

I do my own basic maintenance, but a timing belt is way out of my comfort zone. But, I don't mind timing belt cars, since I'll get the water pump changed at the same time. Many water pumps will need replacement before 200K anyway, and it's not exactly an easy/cheap replacement on the 3.5L either.

On the safety front, side torso/curtain airbags and stability control were optional from 2004, but the side airbags didn't become standard until 2006 and the stability control 2008. A lot of used vans don't have this optional equipment.

 

As others mentioned above, I vote 2009 or 2010. Has the vvti line and oil cooler fixes, and other things mentioned above.

 

I think 2007 is the best. I have 308K and still runs like new.I did replaced vvti line and oil cooler with metal lines at 130K

 

2007 has the same engine as the 2008-2016 Siennas. It's just as good of an engine as the 2009-2010 models, besides the VVT-i actuator issue that doesn't seem to affect too many owners, but most (the overwhelming majority) of used ones on the market won't have the metal VVT-i or oil cooler hoses, which a used car buyer would have to factor in.
