Luxury vehicles are an example of a luxury good. When income drops, people buy standard or economy vehicles instead

In economics, a luxury good (or upmarket good) is a good for which demand increases more than proportionally as income rises, so that expenditures on the good become a greater proportion of overall spending.

Luxury goods are in contrast to necessity goods, where demand increases proportionally less than income.[1] Luxury goods is often used synonymously with superior goods.

The word "luxury" originated from the Latin word luxuria, which means exuberance, excess, abundance.[2]
