I tracked the price of used cars listed on the Tesla website for the last 4 months. In total, I tracked ~3000 cars. I focused on cars listed in the San Francisco Bay Area. I used a linear regression model to determine what factors influence the price.

Some insights:

• Model Y and Model 3 cars are listed for 5 days on average before being removed/sold. Model X and S take a little longer, with an average of 7 days.
  
• Tesla automatically lowers the price if a car does not sell. On average the price decreased by $200 per day.
  
• 68% of all cars have basic Autopilot, 29% have FSD, 3% come with Enhanced Autopilot.
  
• 99% of eligible used cars include the Acceleration Boost option.
