The HUD is exposed to intense sun and heat during normal car operation. That said, along with the interlaminar film in the region where the HUD display is projected, there is a UV film adding a bit more protection of both the HUD dashboard and the people in the front seats.
I would be concerned about the longevity of the finish on the PU-coated steering wheel if the car was to be persistently left in the sun (mine is not, when and where I can help it). Cracking bolsters on seats is an unresolved issue.
I am not concerned with gathering oodles of spare parts, as if the VF, on the premise of this thread, is my last car - - it's not, and it will likely be gone (traded) 4 years from now. It probably will not be worth much at all, being a 'dead brand', not at all helped by events that have lead to the present circumstances with Holden. I am of course speaking about the lower spec VFs. High spec cars may attract attention but the aforementioned points of components still bear weight on the used car market and lookers and/or buyers will be very, very wary.
There are other practicalities and annoyances. The lack of updates to MyLink, and particularly maps, and phone connectivity (no Apple CarPlay or Android Auto, save for aftermarket mods thst do not appeal to Mums and Dads) is a very real disincentive for used Holden buyers. Current maps from 2017 and 2018 are missing 44 new suburbs and satellite estates around Melbourne, and many estates, new roads and anabranches close to where I am - - clsoe to useless. Google has them all. Holden does not. Effectively, VF Series maps are only useful for regional areas one is not familiar driving in.
Bits and pieces that require replacement through wear and tear will be available for a long time. Advice to the wise: do not horde them when others are entitled to spare parts too.
