You don’t need to buy a new car to get a backup camera (which is life-changing, by the way), you just need $82, and a few minutes to run the wires. This model attaches to your license plate, and runs to a special rear view mirror that attaches in front of your existing mirror.
Oh, about that mirror...it has a dash cam built into it! Just pop in a microSD card, and you have a backup camera, plus a dual-lens dash cam to record any accidents.
