I keep a note book in the glove box and write down everything I do to the car...o/c, rotate, pads, belts, etc., I mark the date and the mileage. I do pretty much everything myself but someone who relies on a shop should keep a record and question when someone says you need to replace something. How many miles and how much time has elapsed? If you’ve kept a record, at least you have something to gauge by.
