Transportation To Appointments For My Mother

We need transportation for my 90-year-old mother She has physical therapy, allergy shot, grocery store and other appointments throughout the week, at various times and days, We would try to combine appointments to specific days/times for scheduling. She uses a walker, can get in and out of the car, but the walker will need to be put into and taken out of the car for her. Would be helpful to open the doors on car and at the appointments for her, She can get around on her own. Preference on vehicle is a smaller , or 4 door car, lower to the ground, no trucks or vans. You'll be responsible for transporting to/from appointments. She lives on a hill, road is typically plowed but may have winter road conditions. Preferences is for a caregiver who is female, non-smoker, no perfume, and COVID/flu vaccines.
