Here's a warning I wish someone told me about the rental
Stay in touch with your car repair company to learn when the car will be completed.
The repair company might be contacted by the insurance company before you
learn that the car is finished. This happened to me.
Minutes later about 2pm the insurance company called my home phone to leave a message that as of 6pm that evening they were no longer paying for the car.
That was a big surprise, since I had business plans that night and the repair shop was closing at 5pm. I asked for an additional day.
They refused. I had to accept the charge, but when I returned the car the next day, the rental company said they would pick up the extra day charge.
