Thanks to those of you have replied. Much appreciated. To further clarify the situation, I would be purchasing this Lexus from a family member, and he's pretty conservative and quite meticulous, so I am confident he has not been abusive to the vehicle in terms of driving it hard or neglecting any routine maintenance. He just spent $1,100 on a maintenance job and everything has checked out OK. I don't know about the timing belt, though. I'll have to ask about that. He had new tires put on last year and the interior and exterior are clean. Any additional thoughts?
