Funny you mention that, here in the UK, like in most of Europe, cars have DRM already. As such you have to go to "authorized" garages, where they have to reprogram the car computers every time they replace the part. The result being that they can charge you Â£300 to replace a headlamp.
Classic cars (80's mostly), anyone can do it, and it is cheap (I had my alternator replaced for Â£35, including parts cost). When I tell people that their jaws drop, as their yearly checkup alone costs a few hundred. That is why I never owned a new car.
The thing is, so many people have realised the same as me now, and have started buying classic cars, that classic car insurance premiums have been increasing rapidly. Car insurance companies have taken to refusing to insure classic cars because of demand, unless you can provide you will not use it as a daily driver (i.e. you can only have a classic if you own a modern, and the classic is only for meets, shows and the occasional drive).
It is becoming harder for me to keep mine to be honest because of the switch, and I wonder if in future there will be a bigger push to restrict people from the classics.
It is interesting to note that the largest rise in classics I've seen corresponds to the years when European new car sales have been flat or shrinking. I suspect causation.
