I bought an AP1 Tesla just before they started shipping AP2. I kept my AP1 because I doubted that they'd really be able to ship FSD anytime soon. Shortly after, a friend of mine bought an AP2 Tesla. For the next year, my AP1 performed much better at the features either one provided -- adaptive cruise control and lane-keeping -- than his AP2. And now we're at the point where it's "just kidding, you really need AP3." Still with no end (FSD) in sight. Two years down the road, and no regrets keeping my AP1.
