I read somewhere that a 7 series BMW total cost of ownership was 20% higher than the equivalent Lexus model.
I don’t own either, but I know which way I would go.

And I befriended a certified BMW mechanic in the last few months. He tells me never to buy BMW’s. This straight from a certified Beemer dude. His words, not mine.
