His Chrysler 300? This thing Wikipedia describes as a V8 powered “full-size luxury car”? https://en.wikipedia.org/wiki/Chrysler_300
It's usually a greater-than decade old vehicle, common in the early-mid 2000's. Luxury cars (especially American luxury cars) have a trend of being extremely inexpensive to purchase compared to other vehicles when the age vs. their original price. For example, a similar year Toyota, Subaru, or pre-CVT Nissans will hold higher values than equivalent American brand vehicles, with some exceptions.
Cars move down the economic ladder as they age. A similiar year Camry, Accord, or other InternetApproved(TM) cheap to run commuter car, is going to be in much nicer shape because it started a few dozen rungs higher than that '04 Impala, Sebring or whatever domestic we're comparing to. The price will reflect that niceness.
The Camry that's the same price as the average '04 Impala is going to be in equivalently rough shape and will be an older model year because it took it longer to get to that point because it started in nicer hands.
Seriously, punch in a $3000 price limit into your preferred classified section and see what it gets you.
These people are poor, not stupid. They're buying Big3/Korean/VW/Nissan sedans because that's what's available in the best condition and lowest miles at that price point because nobody wants them because they're not as practical as crossovers and people making white collar money don't fetishize them as ideal beater cars the way they do Toyotas and Hondas of that era.
