How to get an oil change at AA Auto (Purrfect?):
1. Bring your car in and ask for an oil change. Give them your keys.
2. Look ultra-concerned when they tell you that your car needs $900 of repairs. Furrow your brow and nod your head. Say things like "wow, that sounds bad" in hushed tones.
3. Tell them you need to go sell a kidney to fund your car repairs, but you'll definitely bring it back in a few days. Ask for a printout of all the recommended work. Pay for your oil change.
4. Take the printout, which has now mysteriously ballooned up to over $2000 worth of work (including the timing belt, which you just had done less than 5k miles ago), wad it up and throw it in the trash.
5. Drive your car, which is purrfectly fine, another 3000 miles and repeat the process!
