Used cars start as new cars, and after three years if leased, or six to seven years if purchased, they get sold or traded in to make way for a new replacement. So why are fewer of these cars coming onto the used car market? There seem to be many reasons, but we can group them under these three headings:
In a typical year, some 17 million cars are sold. In 2020 that dropped to 14.6 million. Some of those cars go to rental companies, which sell them on after a year or so. Hardly anyone was renting last year, so the rental companies stopped buying new vehicles. What’s more, you may recall that through March and April 2020 just about everything was shut down, including car dealerships. That meant for a while hardly any new cars were sold.
In parallel, people seem to be holding on to cars longer. Reasons for this include not driving as many miles, (because they were working from home,) and the high price of new cars. Linked to this, it seems more people are buying their car when the lease runs out, in part because they’re worth more than what they have to pay the lease company.
Last, the pandemic almost brought car production to a halt during the second quarter of 2020. Factories were shut or staffed by skeleton crews, and when they did start up it took only a single positive test result to send everyone home again.
Then, as the factories began ramping up output, a funny thing happened: they couldn’t get the semiconductor chips that run so many of the electrical systems in modern vehicles. It’s believed this is another consequence of the pandemic: chips went into the gaming consoles and laptops everyone bought while they were stuck at home, leaving too few to meet demand from automakers.
In response, carmakers scaled back production and focused on their higher-margin models. (This is one reason new car prices are up.) So, people looking to buy a new car are finding there are fewer to choose from and the prices are higher.
