We have used this vehicle hard as our kids grew up and it has handled it well. I haven't spent over $1500 in maintenance during the 8 years I have owned it (window motor, back hatch handle, couple of oxygen sensors and a set of struts)
I've owned Sienna since new, lots of miles and no major problems. The vehicle has been serviced regularly, nothing out of the ordinary or short of expectations. It's not as roomy as our previous Caravan but it has NOT been to the dealer for drive train issues inside of 40k either like the Caravan!
After 8.5 yrs and 87000 miles the van has been very reliable. apart from regular maintainance, we haven't done anything to it. we did a 3000 mile trip west with 7 people last summer and got 35 mpg. apart from a rust spot on the right door, the van looks new inside out. My wife told me that when we are ready replace it, we will get another Sienna.
Never thought I'd own a minivan but I needed the space. Test drove tons of them, bought the Sienna and love it! Thought I would keep my '03 BMW 325i wagon but ended up selling it. I enjoy driving this van and it's so plush, not cramped at all like my wagon. Handles surprisingly well for such a big vehicle. If you're having trouble letting go of your car and feel like you're too cool to drive a van, get over it! The Sienna is awesome and fun! Great sound system. JBL speakers rival the Harmon-Kardon in the BMW. Mileage is awfully good, too. Love it, love it!
We bought this van at the end of the 2003 model because we liked the interior better than the newer 2004 model that was being sold. We've put 144,000 niles on it and see no reason to buy something new. The repair history has been great. We've used it to transport soccer teams, drywall, furniture and babies. We installed a 2 inch receivr on the rear and use it to tow light trailers on a regular basis.
