The only thing really any use is the AVM (around view monitor) IMO
As @gilders said with the ECS, you will set to normal and leave it, I doubt you will be setting it to firm or braking that hard you will need it to prevent the nose of the car diving. The PHEV will be planted to the road anyway due to the weight of the battery.
The BVM looks would look nice but, there is a red triangle that lights up in mirrors that essentially serves the same purpose.
The remote park assist is IMO another gimmick , as it will only allow the car to travell backwards or forwards to get in/out of a parking space remotely. It would need the cars parked either side to be straight in there bay’s.
I’d save my money but, we all see things different in life.
Have a look on youtube at the different features the tech pack has!
