Not necessarily. Lots of people can afford new vehicles, and buy them without much discomfort or going broke.

I have two Toyota 4x4's each with over 400k miles. My newest one a '99 I bought for $10,000, it had 65k when I bought it, it's still worth $5000. That truck has cost me 1.49 cents per mile to drive, I'll stick with older trucks for reliability and actual cost to drive

I at least need "four wheels and a seat", where's the seat?

I've drove old crappers my entire life. I bought a new one a few years ago and I'll probably do it till I die.
