yes they are. rich people get loans to buy expensive things instead of giving up the cash, often collateralized by their other toys/stock/trust fund/whatever. rich people also overspend, over-leverage, and overindulge just like everyone else.
the difference is they call up their banker and accountant instead of filling out a form at the dealership.
if you're expecting an asset like a 918 or 911RS or R to go up in price, you'd be stupid to not leverage your cash at a low interest rate and put the rest of it to work somewhere else. at this point it becomes a business move, not a trip to the mall. it's like financing a construction project.
do you think they buy jets and yachts and big homes in cash also? of course not. they setup holding companies and finance the purchases, and then charter or rent the asset out to make some of the money back and to pay the crew of people that run these types of properties. that's why you can rent an amazing vacation home for $1k a night, or spend a few days on that yacht with a bunch of friends for $5k, or rent a ferrari for a few hundred bucks.
rich people are exceptionally good at monetizing and leveraging facets of their life that look like giant expenditures to you or i. poor people try to emulate this behavior, and meet their financial ruin, because they aren't savvy or rich enough to make it work.
