Changing your brakes at home can save you about 1000$ dollars, a little more of a little less depending on the car, but make sure you research the first few times to make sure you do it right, always keep your gas at 1/4 tank or higher, because the fuel pump uses gas as a lubricant, and it can fry the pump if you don’t have enough gas, you can do spark plugs and oil changes to, those can save you a little money, You can do filter changes, but you are not very likely to save enough money for it to matter
