I've got a 2018 Model S 100D which I leased for 36 months starting in May 2019. It was a used store model and had about 1700 miles on it so they reduced the price by almost 15k. Monthly payments are $981 but that's with a 15k down payment I had to make (that was the minimum they allowed for me in order to lease). So that means I've paid a total of 15k down payment + 35k monthly payments = 50k to date. You can see the purchase quote below. Does it seem reasonable given current used car prices or am I better off just returning it?
