If you've got a DIY car person in the family and you don't have any auto-related gifts under the tree yet, you might think it's too late to give the gift of car repair. But it's not! One of the most valuable gifts you can give a busy person is the gift of time. Some of my favorite stocking stuffers over the years have been coupons good for a day of doing whatever I want. In your case, make it a coupon good for a day of working on your car without being bothered. If they decide to redeem the coupon and sneak off to the lake, don't try to stop them! In any case, it's a great opporunity to do a little maintenance.
