Hi, I have the great pleasure of owning a 2000 model rx 300se mileage is just comming upto 180,000 one previous owner before myself. What a great vehicle, a very well cared for example with full lexus dealer history. Appart from regular service work, the only additions to service history are timming belt change, O2 sensors renewed and air mass sensor fitted. I know i will be keeping hold of my rx for years to come. Don't be put off by higher miles so long as the history is all there, good luck.
