Buying a BMW M340i New vs Used

If you purchase a used BMW M340i that is 2 years old, then you could save $ compared to buying new, and still have a relatively new model with plenty of useful life remaining. If you plan to keep this vehicle for 3 years then your total cost of depreciation would be $0. Try other age and ownership length combinations, or different vehicles to see if you can find depreciation sweetspots where this cost is the lowest. Hint: Try vehicles between 2 and 4 years old, as brand new vehicles depreciate quickly. Also, if this is a recently released model and buying a few years old isn't possible, consider another vehicle, or perhaps wait until more used M340i models become available.
