May be buried in this vehicle!
 Bought this car new, spent 10 winters with it in Virginia and Maryland and now enjoying sunny southwest.  Only thing that ever failed was an A/C relay that the dealer tried to tell me was a thousand dollar compressor so $16 later the problem was fixed (thanks Internet car forums!).  If you have the 4WD version, you do need to "exercise" the 4WD selection, otherwise the solenoid in the transfer case that brings in the front wheels will lockup and it's not a cheap repair.  Just putting it into 4WD once a month prevents the problem.  Mileage has been acceptable for its size and the technology in place at time of purchase.  I towed a race car and trailer all over the eastern seaboard with this rig, never broke a sweat, never lit up the trans overheat light.  However, the transmission fluid is an issue in the 03 version.  Dealers will tell you it's a permanent fluid in a sealed system that never needs changing.  Not true.  I have an independent repair shop that uses the specified Toyota fluid in it and I get it flushed and filled every 60K miles, even though I no longer tow.  These electronically controlled transmissions cost almost as much as a new engine so take care of them.  If you can find one of these at a reasonable price, you will not regret the purchase.
