Hi! I'm on the fence for pulling the trigger on a Model 3 (AWD or Performance). To fully convince myself (and my wife ), I have done some calculations regarding cost of ownership of buying a Model 3 vs keeping my M235i. I bought my M235i in 2014 for 52K MSRP (paid cash). I got an offer last month for 30K. I anticipate its cost of ownership over the next 3 years to be about $22650 (including additional depreciation and maintenance). If I compare the cost of ownership of a Model 3 AWD ($19280) and Model 3 PD ($23920), the numbers are very close. You can see the breakdown of my calculation in this spreadsheet. I would appreciate any feedback you might have. Thanks!
