2004 Toyota Sienna LE 7-Passenger Fwd 4dr Minivan (3.3L 6cyl 5A)
I'm a a person that vowed never to own a minivan but 3 kids later I went for it. The Sienna is the best car I've had. The interior space is great and really have had no problems, just regular maintenance and tires. Brakes were need at 50k but that is to be expected. We have a large tent trailer we tow and it pulls like a dream (we got the tow package). The only thing I would improve is the underside clearance. When towing (and even when not), you need to be aware of the clearance. It rides very low and you can bottom out if your not careful. I've heard all minivans are like this though.
Interior space, flat folding 3rd row, smooth riding and turning.
Increase the clearance, but this is mainly due to the flat folding 3rd row. I guess one needs to choose which is their priority.
