Edit due to new thread: Google spreadsheet to estimate Model 3 costs and payments by @LookUp Code: https://docs.google.com/spreadsheets/d/1-Yvl42yfPuBpqjlK73cbOlmw2waoGozFIKwYfY4DBws/edit?usp=sharing @LookUp this is awesome! I did a lot of this on a napkin a week ago and ended up just as confused. The spreadsheet makes it really easy to toggle values and see what the end result is! But why are on earth are you spending $75 on oil changes every month?!?
