Also today, one of the teaching fellows will be sending out a sample concept sheet, although you may have already seen it from the website, but in addition to that, a series of instructions.
By setting up a few simple Excel formulas (nothing more complicated than addition and division, you can see what they look like in this sample spreadsheet), you can not only track your maintenance data (what the mechanics did, when they did it, how much it cost, and what the mileage was at the time) but also see your average daily mileage during each period between servicings.
