I am in the process of considering buying a Lexus Gold Package ES300, mileage: 171260, Year: 1994. The car is in excellent condition the only issue with the car is that it needs a Water pump and seals. What might be the average cost to expect to replace the water pump and seals? The selling price is $3000.00. Would 171260 Miles on this car be to much for the asking price plus the repair needed for the water pump?
