 We purchased a used Sport Trac from CarMax with approx 48,000 miles. Got a great price on the vehicle. Vehicle in great condition at time of purchase. Within 2 years, had to replace the engine in the truck. (Replaced with a case engine, not new.) Today, (08/06/08) the transmission is smoking and appears to be shot. The vehicle is squirrely to drive. Would not recommend this vehicle to anyone. CarMax was great, but Ford was not in the situation. I have an F-150 with almost 200,000 miles, and would not trade it for anything, but Ford really missed it with the Sport Trac! Buyer beware!
