VIN 1986 checking in for a data point:
1044461-02-B (rear driver)
1044364-01-D (front driver)
Our other car is a P85D with the early + suspension, so I trend OK with stiff suspension. I don't find the 3 to be harsh, but it is a bit "bouncy" in a stiff way which I attribute to the coils vs the P85Ds air. Neither are fun on rough surface streets.
I don't know if I would ask to swap out for the newer dampers. Would want to drive one first, so would have to wait for test drive cars to be available I would guess. I wouldn't want it to feel like a "standard" model S with air, but would be OK if it was closer to my old P85 with coils, which was really nice.
