It sounds like you've given up completely on what a car infotainment could be because car companies suck at software so bad.
I had an old GMC Canyon through college, and the only thing it had was Aux. After college i bought a model 3 when they first came out and I absolutely love the infotainment system. I love that I can play witcher 3 on my Tesla. My bluetooth always connects. I can unlock my car with my app and it never fails me.
Not the OP, but I have. I’ve driven cars from cheap econoboxes to exotics and all of them have had mediocre infotainment and navigation systems at best.
At some point it will fail. You will not be able to fix it yourself. And if it is even fixable, it will cost you a fortune to fix. Let's talk in another 10 years and a few cars later how you feel about it then.
Tesla's hold their value better than any other car on the market. In 10 years, i'll spend an order of magnitude less on maintainance than every other car on the market.
