Fun fact: Porsche offers this for some of its older generation models.

Yeah, Porsche is the only manufacturer that I know of that actually cares about older cars they've sold.

They even made an amusing ad to that effect: https://www.youtube.com/watch?v=R8-9oIq1hxw

Mazda upgraded 2017-2018 systems with carplay after sale. It cost some money at the dealership but it was a standard procedure they could do

You're effectively saying that you want more disabled features, just in case you want to upgrade your property at some point.

Not really. CarPlay didn't exist when the car was made. The car manufacturer had to add software integration even if the hardware was already competent. Parent comment is saying they'd pay to receive this added integration.

No, they're saying they would pay for new software. Many ~10 year old cars have all the hardware necessary to support things like CarPlay, but because CarPlay didn't exist yet they do not have it. A lot of people would probably happily pay $200 to add it to their car without having to shoehorn in a third party head unit.

I think it was more about offering features on cars manufactured prior the new feature was released...
