I second the CAA recommendation. Been with them since I started driving about 20 years ago. Roadside service is great. Battery boosting, will bring you gas if you run out, will jimmy your locks if you lock your keys in.
I would go with the "plus" membership as opposed to the regular. They will tow up to 250kms as opposed to 10km with the basic membership.
Check out all they offer on their website. They have ticket discounts for amusement parks, hotel discounts, we booked our honeymoon through their travel agency.
Kudos to you for offering her some guidance.
