Gotta agree with Tricia here. Who knows how much money she’s getting if any? Let’s say she’s coming into $1 mil. A $60K car means nothing to her, exp. if she is investing and using the interest to live on. Now, if she is only coming into $100K than buying that expensive of a car would be considered by most a bad idea.
On topic: I would honestly go with the Mercedes, of your first two choices.
