Expected Expenses for the Car Repair

I’m making some list here of our expected expenses for the car because our mechanic will have his general check-up tomorrow. I’ve listed battery, reserved tires, wiper motor and many others. I’m thinking if we’re going to buy a new car audio since the existing one is good enough for us. Hope the mechanic would see lesser trouble because repair expenses will definitely affect our budget for the holidays. Anyway we listed the car now as one of our priorities because we’re going to use it for our camp meeting and before the actual camp when we’ll be bringing the instruments to the site. I have plenty of things to list but I just prioritized the major ones because the minor accessories can be bought at a later date.
