500k a year surgeon has no time actively managing a rental property. It is a lot of work and only for those with lots of free time and are very handy and not afraid of getting dirty, like my retired dad.
If he wants an LC, that's not inappropriate, he earned it and can afford it. Many don't want Luxo Euro badge because of the perceived reputation of some of their owners (not all, just some). Plus LC is probably the most reliable SUV in its class, and highest resale value.
500k a year surgeons drive all kinds of cars: Porsche, BMW, Mercedes, Lexus, Toyota, Honda, Ford, GM, Cadillac, Tesla, Nissan, Hyundai, Mazda, Acura, Infiniti, etc. They are people just like the rest of us.
