Thank you for the thorough comparison analysis. I priced out an M550 just for giggles, and it was almost $100k! That to me is ludicrous, but I've been spoiled by having a father and grandfathers that retired from Ford (my father was Exec level). I usually pay around $250 - 280 for my leases, and that includes my loaded 2017 and 2019 MKZ's. My Conti is a bit more, but I purchased that CPO, since they are no longer produced.
I feel like Lincolns are an amazing value for what you get. I'd love the extra HP of the M550, but in SoCal traffic I wouldn't benefit as much from it as I do the luxury features like the HUD, soft close doors, and the rear seat package. When I 0ick my kids up from school in this car, everyone calls it the limo, haha. They do use these as limos at airports, I remember a vendor picking me up in Chicago in a black Conti once, and it was a comfy ride after a long plane trip.
It's too bad the marketing is so horrible (or non existent) for Lincolns. Everyone I run into here says they've never even seen a car like mine. In the OC successful ppl drive a BMW or MB, and consider them a status symbol. More dealerships are adding Black Label showrooms however, so I think things will start changing.
