I recently took delivery of my S75D about a month ago. At the time I had to decide between the 2 year lease or buying the car. I'm in line for an M3, so I *may* end up trading in this car in two years or possibly less. The AP2.0 announcement has made this even more likely. Here's where I'm confused. I made the decision to buy because - according to my math - it seems to make much more financial sense. However, most people say 'lease if you're keeping the car for 2-3 years'. Here's my math - can someone let me know what I'm missing? The 'out the door' price of my car was $73,216.25. This includes $9,700 in discounts ('showroom' discount for brand new car, referral credit, waived destination fee, and federal tax credit). Basically what I paid out of pocket. Lease: Due at signing: $10,375.75 (VA sales tax + registration + leasing fees + $6,000 down payment) Monthly payment: $695 Total cost to own (2 years): $27,055.75 Buy: The total cost of ownership is entirely dependent on the resale/trade-in value in 2 years. Here are some scenarios: $55,000: $18,216 total cost of ownership $50,000: $23,216 total cost of ownership $45,000: $28,216 total cost of ownership $40,000: $33,216 total cost of ownership So - as long as I can sell this car in 2 years for at least $45,000, I come out either the same or ahead of leasing. Now, I know that *no-one* can predict resale values, especially with AP2.0 (and soon M3) out in the wild. But I am a low mileage driver (less than 1,000 miles a month). I also expect the eventual expiration of the tax credit to help used Tesla sales. Don't you think it's a fairly safe bet that this $73,000 car could go for $45,000 in two years? If so, what am I missing in the lease vs buy argument?
