I purchased my Expedition 3 years used with 33000 miles. It now has 125000 on it and I have not had any problems with it. I've taken many family trips all over without any issues. I wish that all the vehicles I've owned were as trouble free as this one. I have no plans to replace it and hope it continues to run forever.
Great in the snow. Good towing ability. Seats are comfortable.
As with all large SUV's, be prepared to buy the required gas.
