Loans appeared almost immediately alongside the invention of the private motor car (~1920 Ford/GM had to start offering financing on private vehicles to make them affordable), with 60-75 percent purchased this way in the 20s. Today its 85 percent - there wasn't really ever a period private car ownership didn't involve finance, at least in North America.
> Remind me if I’m wrong but didn’t something dramatic occur financially in the 20s?
"The practice of Americans buying consumer goods on the installment plan dates back to the Civil War," e.g. for sewing machines [1].
America's first affordable car, the Model T, was released in 1908. In October 1919, less than one year after the Armistice of November 1918 and just four months after the Treaty of Versailles, GM had "created a financing arm called the General Motors Acceptance Corporation (GMAC)."
You said "cars became 'unaffordable' sometime when loans became common." That is wrong. Cars became cheap because of industrial production. Production aimed at the American consumer, in part, due to the post-Civil War prevalence of installment-based purchasing of factory-made goods.

Hopefully we won't be testing FDIC coverage with them...

The flip side of limited recourse is limited liability. For houses, non-recourse lending promotes speculation, volatility and risk shifting [1]. One would expect similar effects if non-recourse lending were normalised for cars: higher prices, bigger booms and worse busts.
