For $1,200 more you get AP1, Air Suspension, Dual Charger, and 20% less miles, but stock black paint instead of grey metallic. Draw your own conclusions as to how much AP1 is worth out of that price difference, however no way is it worth any more than $1,000 on a CPO.
I'm not dissing AP1, just stating some pricing facts. If you're interested in my personal opinion, I would be willing to pay up to $750 for AP1 for *my car* but would not want AP1 or EAP in its current state for my wife's car, as she is not a techie and I would see AP1 or EAP a potential hazard (IMO she would start trusting it too much and end up in an accident - almost happened to me and I'm an engineer who works on things like this so I should know better). I would pay $250 for TACC (but no auto-steer) for her car. Will pay Tesla $10K for FSD if Elon delivers on his promises, i.e. the car can drop be off at the airport, go back home, come pick me up a week later when I come back from a business trip - all while I am in the back seat, nobody in the driver's seat.
There are a couple of other factors at play including tan interior on the AP1 car. Comparing nearly identical cars to one another on the CPO site, I've found that black interior usually commands a premium over tan interior, with gray being somewhere in between the two.
