I can't think of anything that endears 3rd gens to motherly types unless they like the look of the car. They are good-looking and ride on a pretty good platform. They can take a beating and will last a long time if taken care of. Well, maintenance on them isn't too expensive either since parts can be found everywhere for a dime a dozen.

You may try the "this is what I really have my heart set on... pleeeeeeease." method too. That pulls on the motherly heartstrings.

Good luck.
