I very precisely worded it as "total cost of ownership." Really, how difficult is that to read and comprehend? "Total cost" does not correspond to "annual maintenance."
You're not paying me for my financial planning advice, so I won't spend the time breaking every single line item out for you, but here is an overview so you can get the idea into your head:
On a $250k salary in Seattle, you'll be left with under $150k after tax. Say you live in a nice upscale apartment like this one. I don't know the multifamily real estate market in Seattle but I can ballpark that a nice 2 bed condo in Bellevue will rent for $6-8k/mo. I assume if you look up the average rent of this particular building I wouldn't be too far off.
So you're a hot shot SDE III at Amazon (you know, the one in ten that actually gets promoted at that company) finally vesting his 5th year stock options and cracking that quarter mil. You live in an apartment that makes your friends jealous and your parents proud and you finally think you can afford a super car. You go out and buy or lease an "entry level" Huracan or 488 GTB and somehow get approved.
If you lease, you'll pay about $3k a month. If you buy, you will eat not much less than $3k a month in depreciation unless you almost never drive that thing. Did you think insurance would be reasonable on these cars? You can add at least a $1000/month insurance differential over whatever plebeian commuter you were driving before you got your Lambo or Ferrari. Obviously that's variable with age and location, but we're talking about the scenario of a relatively young Seattlite software engineer.
So now you're at $48k a year just in lease payments/depreciation and insurance alone. My $65k figure was from a similar scenario I worked out as a cost-analysis for myself and a friend. That figure also includes things like gas, tires, brakes, and sales tax. If you scratch a single rim or someone dings your door, you're way over that.
So after $65k/year on your car and $96k/year on your apartment, you just spent more than your entire post-tax income on a single car and condominium and now you're broke. Congratulations.
No-one in that apartment with a super car is a mere "well compensated tech guy" unless they're a late series startup founder, a principal engineer, or they're over-leveraged to the point of financial ruin if the tech industry ever contracts. I don't mean to shit on your dreams because you sound like an optimistic young guy, but $250k+ super cars isn't something a W2 worker can (or should) strive towards just by dutifully turning up their job and putting a chunk of their paycheck away into their IRA or Vanguard. Investing isn't just "a thing too," you just don't make Lambo money off a $250k paycheck and 8% returns on a humble retirement fund.
Also, Ferrari does not have free 7 year maintenance. It comes with 3 years free, and 7 years is an option you have to pay for. It goes to show that you're out of your depth with your knowledge of super cars. Don't mean to be condescending as I wrote this whole thing for your benefit. You just have to temper your expectations about the affordability of these types of cars and think in terms of numbers, not emotion.
