I'm considering buying a 2011 Sequoia from a dealership. It has had one owner. Because he was in sales, he put 40,000 miles average per year on the vehicle. It has 159,000 miles on it. It is unbelievably clean. The dealership checked it out and sees no problems. It has good Michelin tires on it. They are asking 18,900 firm (after already coming down from 20,399). Any thoughts on this make and model, mileage, or price?
