I don't like spending money on cars at all and always buy those for about 3000$ and use them for a few years. I treat them like crap, wouldn't be worth it in my case.
I often use company cars and they are always nice and comfortable, but I didn't encounter any software system I like yet.
I my car I rig my smartphone to the audio and have all features with slightly worse ergonomics.
Maybe interesting for families that often drive on trips but I don't really see the added value yet.
But, it would actually be interesting to get more technical information about the car. But these are hidden by the shitty proprietary software in cases I encountered. And of course you don't get access to maintenance information without manufacturer specific devices...
It was expected that manufacturers try to roll their own systems and try to hide actually useful info in favor of some fucking internet music store. Disappointing.
