When it comes, that collapse will, at least in part, be due to the fact that over the past 6 years, new leases, as a percent of overall car sales, have soared courtesy of, among other things, low interest rates, stable/rising used car prices and a nation of rental-crazed citizens for whom monthly payment is the only metric used to evaluate a "good deal"...even though leasing a new vehicle is pretty much the worst 'deal' you can possibly find for a rapidly depreciating brand new asset like a car...but we digress.

Of course, what goes up must eventually come down.  And all those leases signed on millions of brand new cars over the past several years are about to come off lease and flood the market with cheap, low-mileage used inventory.
