Here's a clue, ALL Luxury Cars and SUV depreciate at a rate faster than a regular car or SUV. Additionally CarMax is one of the worst places to sell your car or buy one, unless you need a fast sale.
One has a choice when buying vehicles, pay cash, my preferred method, buy and keep 8-10 years with loan, great when it is 0.0% no reason to pay cash or lease. 1 car payment, multiple car payments then done or lease forever, make a choice it is not hard and there are pros and cons to each, no method is superior to another either, it all depends upon your finical situation.
I personally do not like leasing, mainly I don't like the third party leasing company involved, it is not for me.
