Welcome to the nation! Sorry to hear about the accident, but at least it sounds like your wife came out okay.
As for the Highlander, I'm a 2008 owner and have had mine for 18 months. IMO, it's the most enjoyable vehicle I've ever owned, and I own a Base model at that without all the bells and whistles. The only issue of significance with the Highlander (and this varies among owners) is that it can be prone to interior rattles and noises. Toyota says this issue is being addressed, so one would hope the 2010s will be quieter. Other than that, it's an outstanding vehicle with phenomenal mileage: 19/20 city and 27/28 highway for me, and that's a non-hybrid V6.
