It doesn't matter if you buy, borrow, or lease -- those first three years will end up at around $2k/month.
If you plan to keep the car for another 5 years, and pay it off with a 5 year used car loan, you might pay about $1400/month or so, after which point you own the car outright, and maybe it's still worth something at the end.
The way I see it: The other cost is insurance and maintenance, and we don't know how well these will last past the warranty period -- if we believe it's solid, it's cheaper to keep the car rather than get something new. If we want something new, it's either back to $2k/month, or buy something along the lines of a BMW i4 M50... (Or a Chevy Bolt, which saves a lot of money! :-D)
