I borrowed this 2001 Lexus RX300 from a friend who is a used car dealer. The SUV looks good inside and outside, and drives well. This may have been a fleet vehicle because he got it from an action (gotta double check). The major worry right now is that it has 187 thousand miles on odometer. The dealer wants 5,700 for it. Is this SUV worth buying for this price and is it worth buying at all?
