I test drove one when we were looking for a replacement for the Highlander and found it to be a good overall X-Over. I did like the comfort and available space but was disappointed with the interior styling and material. Contrary to what Chris writes I did find it underpowered as it is a heavy vehicle.
At the time it was a real contender but has fallen somewhat due to recent releases in this segment. I always go back to out Highlander ownership experience as a benchmark and unfortunately that set the bar very high.
