Scumbags want an easy quick steal. Anything you can do to deter this will
help. Posts on the drive will
help as will security lighting and camera’s.
Taking extra time whilst lit up and on camera is a deterrent. Make it shown that you have these and I’d think you’re likely to be left alone.
As for the CUPRA, rebadging will
help as will getting smaller wheels. However you will be ending up with a car that you didn’t actually buy. It will be made to look un-CUPRA and drive un-CUPRA.
I think what you’ve got planned (and done) to your property to deter scumbags is the best idea.
As for the CUPRA go for debadging only (and maybe Black exhaust tips). The brake callipers on the new CUPRA are Black so no need to alter those.
Good luck with what you decide to do
