I think it might depend on what someone means by "luxury car". An affordable sportscar like a Miata or a Scion FRS doesn't seem all that unreasonable.

The other things (home, family, decent job) certainly don't seem unreasonable if we weren't living in a late stage capitalism dystopia.

Luxury cars have industry definitions and colloquial definitions. Miata’s don’t fit the industry definition, and I don’t think I’ve ever heard someone call a Miata a luxury car.

The person in the article is most likely talking about a Lexus, Mercedes, Audi, BMW, Volvo, Acura, or Infinity.
