Hold on.. if the selection on EV-CPO is "not good" that means the selection on Tesla.com is "not good", as EV-CPO lists every car that's listed on Tesla's own website. The selection is actually quite good as I have people constantly telling me how they found the car of their dreams from the website or from email alerts generated from the website. Sure, since the inception of the CPO/used and Inventory programs Tesla has always held back cars that they never list online and are only accessible to sales associates. But that doesn't make the online selection "not good". I will always recommend to people to use both methods to find a car that fits their criteria, and the car they buy could come from either source.
It happens quite frequently that large batches of cars are removed all at once. EV-CPO constantly scans the Tesla website for changes (not 'hourly' or 'daily'). This example is only eight cars because the source data is only the screen shot in the first post of 22 cars. Both the original number of cars priced at $82,900 and the number of cars removed in bulk at 6:32 are likely much higher. Somehow I doubt that all eight cars were all sold within minutes of each other.
