Bought one new in 2000. Currently at 210,000 KM (130,000 miles) Have replaced brake pads once at 120,000 km. Other than that only regular maintenance. Driver side power window motor sounds like a bearing is worn. Kids are older, probably will sell it and get a smaller more fuel efficient vehicle. Paid 29,000 CAD in 2000, can sell easily now for about 8,000. No complaints here, obviously.
We bought our '01 Sienna new in June of '02. No problems with it at all. I tested several other minivans and was astonished at the power of the 3.0L V6 in this car and that's the principal reason I bought it. It also impressed as being quiet, comfortable and solid. After 62K miles, it's just as quiet as the day we bought it. We've gotten 26mpg on many long trips, which seems good for a van. Excellent features and sound system. The driver's side electric mirror has become a little balky and the power door needs a minor adjustment. NO other problems. Our experience with this has led us to buy two more Toyotas since, which are also great cars.
It's very, very quiet. Standing near it you can hardly tell it's running until the fan kicks in. Far less engine noise than a neighbor's much newer Chrysler minivan. Extremely comfortable seating. Like the adjustable rear seats for adjusting passenger comfort/luggage room.
Tires wear more quickly than I like. I get, at most, 40K miles. Significant understeer. Both acceptable for a 3900lb minivan but improvement would be nice. Heat is a bit slow to come on and, if the A/C could be disabled in defroster mode, that would be nice.
Drives like a car. Purchased for its reliability and safety rating. I wanted something safe for passengers (children in the car.) It has lived up to all expectations in terms of comfort, performance and reliability. We are on the highways a lot here - no complaints about acceleration. Excellent turning radius. After five years, still like the way it looks, inside and out.
Comfort. 2 side sliding doors. Easy to use rear door.
Deeper cup holders. Newer models have added side passenger drop down air bag curtains, all wheel drive, backing up sensors, seats that fold flush with the floor, GPS (although I haven't read how their system compares to Magellan, and are roomier, etc.) Another desired feature: hybrid fuel capacity.
Didn't intend to spend that much when we bought it 5 years ago but it's been worth it. This is my 7th Toyota and it has been just as reliable as all the others. And when I say reliable I don't mean how some people mean it. It now has over 64500 miles and I just changed the brakes, tires at 40000, and air filters every 30000, nothing else on it has ever been replaced. The only thing the 2 dodge grand caravans I've had over this vehicle is interior volume.
Comfortable ride, easy handling, good get up and go for a small engine, good gas mileage, nice lay out. I could go on and on and ....
The inside could be a couple inches wider from the rear door to the front seats. A 4x8 sheet of plywood really messes up the interior. Could also be at least 6 inches longer from the backs of the front seats to the rear door. A 4x8 sheet doesn't fit inside with the door closed.
