I was told all sorts of magic rust preventage gimics when buying my last two cars. Even to a magic gizmo to connect to the battery!!
What got up my nose, were products to protect the paint. OK. If I was always going to park on the street, and UNDER TREES, perhaps some requirement. Also in case I was a beach bum. But like you am happily retired, and living in Southern Highlands, so why promote these items? (in an area away from the sea)
Front and rear sensors, combined with the rear view camera now make parking a doddle. Very glad I included these items.
However have yet to even try out parking assistance!
Have only done about 9000K on my 118TSI, but the enjoyment still increases.
