While it's interesting question to ask, you have to realize that income level is not the only way to measure finances and wealth. There's a lot of factors from where you are in life; young, old, married, kids, single, savings, etc.
A person could be retired, with a lot of savings and only taking out >40k a year from their investments for tax reasons... Maybe they bought it straight up with cash. Likewise they could be young and come from money and maybe they work for a non-profit or volunteer most their time... but their income is low.
On the mid-levels, you're not always comparing apples to apples. If the household income is 100k-120k with two people working and three kids, yeah maybe not a great idea to spend this much on car. If you're on that same level and your "household" is just you, a single person that is a whole different situation.
