Only figure I could find was 40 million used car sales a year:
40,000,000 and 690,000 = 1.75%
Remember that in a recession most will keep the car they have rather than buy new or used. So less go on the market from that as well, but demand will reduce also.
Used cars can be sold multiple times and this idiot government DESTROYED the cars. So it’s a muliplier past 1.75%

BTW, I just bought a used car $2500 below KBB price and just below private sale price from a dealer.
