You probably did not realize that it is possible for you to use your excel program to do a rental vs driving your own car mileage calculator experiment. However, this is certainly the case. You will find that you are able to do exactly that when you use this program to help you with the problem of figuring out if you should use your own car or perhaps take out a rental care to put the miles on it.
That is something that people want to know before they go about doing too much damage to their own car. You too should be concerned with this.
