You definitely do not want to spoon feed her. My point is, you’d not want to give her a known unsafe vehicle and she has an accident where she or someone gets hurt. You don’t want that on your conscience is all. If the car just runs rough and/or burns oil, yet the brakes and tires are good, no worries, say nothing.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
