go and have lexus dealer check out the car for you, it'll cost about $70, they'll tell you the condition and what's coming down the road. things to watch out for are, sludge in the oil, overheating history, drive the car for at least 15 mins and see if it hesitate on stop lights, see if the idle is okay. check transmission fluid, steering and cooling system. if you do decided to get the car, plan to spend 2-300 dollars in changing things like spark plug, filters, wires, fluid change, flush...etc.
