VXOC Astra-J/GTC

I am looking at getting the casada but I am being put off because there are some without front parking sensors or power fold mirrors. can these be retrofited with genuine upgrades or is it a case of finding one with the spec I need which seem to be rare.
I have the facelift J 2.0l elite and mirrors and sensors those are standard and I find this annoying
I am open to advice Thanks

Yes they can be retrofitted.

Parking sensors will most likely have the wiring for front sensors upto (under the battery) it's then a small loom from there which will connect to the a new front bumper loom.

Power fold mirrors again should be a case of adding the wiring as per the astra and of course the mirrors and switch.
