To be honest, the Automotive industry is MAXIMUM POZZ, from what I've heard from Mechanics.
The diagnostic machine that is NECESSARY to even do anything on a car, is something insane like 80K + a yearly subscription to firmware updates.
Cars here are going the route that large appliances did, they are designed to FAIL in an expense way in 3-5 year increments a few times, then you are supposed to give up and just Buy/Lease an new one.

It might just be better to start your own large appliance company like Refrigerators, Stoves and Dishwashers that last for 100 years and while styles may differ, parts are easily found.
Who cares if you only sell 1 per household? With the SHIT quality and scammy workmanship of 99% on the market today, you'll have hundreds of millions of buyers. Then you can move onto other appliances and innovations while still having a good service standard as a model.
FUCK PLANNED OBSOLESCENCE!!
Push innovation into a Neo-Victorian aesthetic!
