FWIW, our '06 LR3 has been about equal in reliability to our '03 GX470 that we had for four years, which is to say very reliable. The only small problems for both can be attributed to both respective dealers, not the manufacturer. Both were and are far more reliable than the ML (frightful), Jeep Grd Cher, Porsche Cayman, and various Subarus I've had.
I now pick my cars by lease/buy, convenience of dealer location, warranty, and loaner car policy; irrespective of reliability ratings. The Jeep and Suby's were very deficient in this regard, and made life a living hell with problems requiring multiple visits. I almost look forward to problems with the LR3 and Cayman, as the dealer location, experience and loaner cars/trucks make it all positive.
