We bought this minivan used from the original owners with 220k kms. When they bought it new, they had a remote starter, class II towing package with trans cooler installed, and the undercarriage was undercoated with rubberized rockguard. We have owned it nearly 7 years and driven 130k kms for a total of just under 350k kms. In the time we have owned it, I have done regular maintenance to it, brakes, tires, engine tune-ups, etc and have only had to replace both rear wheel bearings, all 4 ABS sensors, two inner tie-rods and the original battery. I just completed the 332k timing belt service and the engine runs like a top. It will tow all I need it to and still gets reasonable fuel mileage
bought car brand new. did standard maint. car still runs strong and quiet. now at 150K I did do the timing belt/hoses at 75k. The A/C stopped working 3 years ago. Recharged with sealant fixed it! Interior passenger door handle broke twice... cracking AGAIN! Struts seemed okay, but replaced at 120K due to slick salesperson at tire place. Car runs like NEW. The car had LOTS of short trips, and had many hours run time in crazy long traffic. Now giving it to my son to drive until it dies. Best $22K I ever spent on a car. Previous van Dodge caravan sport SE, just about fell apart at 150K, many repairs and extra maint! (But the dodge looked nicer ;-) ).
Overall, the best vehicle I've ever owned in my 30 years of driving. In about 220k miles, I've done oil changes and paid for tires, brakes, and a new timing belt. Otherwise, it has been perfect. The driving condition is comfortable, and the leather seats have held up well. Removing the back seats is easy, if you have a place to put them. If you want to remove the middle row seats, it can be a pain, but that is offset by the fact that they are very comfortable. Overall, the best automotive value I've experienced (and I've owned one of just about every nameplate). Not sexy at all, but if you are looking for that, you don't want a Minivan anyway.
Bought this van brand new in 1998 while pregnant with my second child. Now 2 kids more have been raised with this van, and it continues to run on the original engine. Very few repairs other than things you expect, like shock/struts replaced. Kept up with oil changes and maintenance and it has been the most reliable thing I have ever owned. Once again, as others, have replaced those darn door handles x all four over the years. Just bought a brand new 2011 sienna, but couldn't give up this one.
I have owned my 98 Sienna for 10 years and am very pleased with it. I drive it to and from work daily (40 miles round trip). Bought it with 60,000 miles on it and currently it has 158,000 and counting. Problems: exterior door handles breaking (common on these models); one interior door handle break; rear intake gasket leak; power window switch. Also had the rack and pinion replaced recently. Otherwise it has been only routine maintenance required. Another dependable toyota product and can't wait to see how many miles I can get out of it.
