Following March 2020, something specular happened to the used car market. What was always one of the worst financial decisions one can make became the investment of the year. Used car prices skyrocketed and for the first time in history, cars appreciated. For example, a used Model S bought in Feb of 2020 on average costs a buyer around $50,000. Today a used Model S will set you back $71,000. A 44% increase.
