There's no mileage limit. So it simple, rent it beginning of the morning at like 7 am, return by closing, 1 day rate, they don't track mileage if you return it to the same place your rented from.
It is more to take it from store a and return to store b .
Don't know if that was an option, but it was worth an extra $50 to not drag an empty tow dolly 100miles for me. !0 miles from rental place to where the car was was like riding a jackhammer. :eek::steering:
