I bought this new in 2005 and now have 65k trouble-free miles on it. After 3 Explorers, it has been very nice not to have to meet on a regular basis with the service writer for a change. 4-cyl is strong enough and gives 20 mpg around town, 25 hwy. Only problem was with original Toyo tires - at 29k they looked great but couldn't keep the vehicle on the road in FL summer rains. New Michelin LTs solved that problem. Only costs have been oil changes, filter changes, and a new battery. Very satisfied.
This is the greatest vehicle that I have owned. Its fun to drive, very comfortable and I would buy another in a heartbeat. I have had several different vehicles including 3 SUVs and I love this one the best. Having the 3rd row is like a bonus. We don't use it much but it is nice to know its there if we need it.
We have only had our Highlander for 7 months but we could not be happier. No problems with performance or engine quality and we changed from V6 minivan to 4 cylinders. Only complaints were with internal finish. We had to have some minor adjustments done to roof molding etc.
Zippy and comfortable to drive. Drives like a car but gives you the extra height and space you need. Very versatile.
