Simple. People value different things and have different situations. I bought the truck for room, comfort (rides better than regular f-150) and ability to get to remote camping. None of these require more than about 250 hp. I would take 5mpg more, for example, and give up 100hp for the privilege. And yes, for some people the raptor, like most luxury items, was a financial stretch. 10% fuel cost is still relevant to the average raptor owner, I would bet. I’ve known guys with lambos that discussed fuel cost, believe it or not. There are very few people rich enough to not consider cost and unless your net worth is north of $10m you better pay attention.
Well, a few things. If you're happy with a down powered engine, good on you, but that's not the context here. You aren't missing anything to save money. Reading the OP's first post he obviously was NOT happy with his down powered engine. He traded a bit of gas money for enjoyment of his vehicle. Is that worth it? Not to me. And, again reading the OP's first paragraph, not worth it to him either.
That out of the way, I don't pay attention because I don't need to, and nothing to do with net worth. You can have a high net worth and lousy free cash flow, somebody who's wealth is locked up in real estate as an example, especially if their primary residence is a big chunk of that. So, I'd stick with a sports car, say a C8, and ability to feed it without worry instead of being a financially nervous Lambo guy, keep more cash flow, and not lock up so much of my net worth in a car I have to be concerned if I can afford to drive. A solid example of financial freedom over net worth thinking.
I just understand the difference between being able to afford to buy something and being able to afford to own something. Combine that with the ability to live well within my means in an area with a low cost of living. I realize people talk themselves in to 'stretching' and lose the freedom to not count nickles and dimes because of that, but it's not me and it's not a lifestyle I "get". I know I can die today, I've no time to worry about gas prices at the expense of enjoying what I've bought.
Which is the point: IF you aren't enjoying it, WHY did you buy it?
