without disrespecting your thinking, this is not really possible to form yourself an opinion without having used / driven both.
The AP1 works very well in simple situation. The AP2 goes still quite significantly above in term of functionalities and security, thanks to the side cameras.
But it goes beyond that: with AP2, you have all the camera for Sentry Mode which is a game changer. If the car would be cheap, you would have a point. But 2017 AP1 Tesla are still very expensive and not significantly cheaper than 2017 AP2 or 2.5 cars. I think because not everyone is informed. I do believe that if you are looking for a 2016-2017 Tesla, having an AP2 car should be on the very top of the list because it gives much more functionality and for a 2,5k€ upgrade, you give it much much more value for the resale than an AP1 Tesla.
I get your point, would be good if people who have owned both could chip in. Still none of the above is carved in stone: Cameras don't deter committed thieves (Pin to drive does but my turbines remain at risk...). I like the AP2 and would have loved to get it but I am very happy with the deal I was able to make on my P90DL. Not having AP2 doesn't make this a bad car, and in turn AP2 might not add any extra value if you don't want to spend the 10k on FSD but just want comfortable highway cruising (which AP1 does fine).
