As a fun little exercise (OK, maybe not so fun), I figured a total cost of ownership for my X5 from May 2015 to March 2018. I factored in everything I could think of: Payments, down payment, gasoline, repairs, registration, city stickers and insurance. I also included the positive equity from the sale of the car.

Total cost for 33 months of ownership: $34,107 (Including ~$9k in gas).

Cost / Month: $1033.55
Cost / Day: $34.45
Cost / Mile: $1.04

Makes for a pretty good argument to try life without a car for a spell when I don't really even need one.
