Fred still insists the reason he came to UMass with $4,000 cash the weekend before Maura vanished was because he was going to buy her a car. Of course, they never did buy the car.
One thing he's never mentioned is what his plans were for the car Maura was driving, which was in his name. Neither he nor Maura had made an effort to put it up for sale. There was no For Sale sign in the window. He couldn't have used it for much of a trade-in, as, in his words it was "running on three cylinders." What was the plan, there, exactly?
