I am looking at purchasing a gx470 and would like any feedback. I have found 2, both 2004 same features (nav etc.) both 1 owners with all service records from Lexus dealerships. 1) $15,000 w/ 111k miles - black with tan - all Lexus services records with water pump and timing belt at 97k. 2) $17,000 w/ 80k miles - dark blue with grey - all Lexus service records but timing belt and water pump have not been done yet. Any thoughts of other questions I should ask. I haven't seen in person or driven yet as they are in Austin about 1hr from where I am at. Oh and both are being sold by the owners. What I think I need to ask: 1) has clunk been repaired with new driveshaft 2) has radiator been replaced 3) have air bags been replaced What am I missing.... thanks
