Can you expand on this Dan?
My first issue is cost. If these things break, they are very expensive to replace, and you invariably have to replace two at a time. Then you have the electronics which also go pop and need replacing. In short, any issues get very expensive very quickly.
There's also the issue with handling consistency. Now, I don't know about BMW here, but the Porsche PASM constantly adjusts the oil rate inside the damper to give optimum grip when in attack mode. That's great in theory, but that means you have zero consistency in the damping which leads to unpredictable handling, as it'll never do the same thing twice. For road use it's fine, for the track it's a nightmare. If the EDC isn't that clever and it's a simple on/off for damping pressures, then you'll be fine. I genuinely don't know on a Beemer!
But yeah, it's mainly the cost issue for me. More stuff to go wrong, which is why I'd only buy a manual car too.
