Lois and giz.
I agree with both of you. There was no mention of JD donating the car on the Sunday (Monday for Canadians) episode. Does that mean JD changed his mind or did/will he just do it quietly? Was he being genuine (typing that word makes me think of Suzie saying "genu-wine-ly" over and over) or selfish or some combination of both? I'm really not sure. That's what happens when you try to judge people simply by viewing minutes of heavily edited footage a week.
