I'd be worried about mileage also if I drove around for 4 hours "shopping"I caught that also. In her defense, when we leased a car, I did calculate monthly mileage because I was so scared to go over. I’d be interested in knowing how close she is to her “mileage quota”... She’s a stay at home mom, younger kids ride the bus, older daughter has her own vehicle, and from my understanding, necessities are nearby.
