You can, however there's three problems.

Firstly from an aesthetic point of view they're hideous, you'll end up having to buy a plastic piece of crap to hold it in and aftermarket stereos are just not great, it won't be flush to the rest of the dash.

Secondly depending on your car a bunch of stuff that used to work with your car (forward/reverse sensors) might not show up any more.

Thirdly stalk adaptors costs a fortune.

You really want a car that has got that experience sorted and after driving a modern VW, I'd say a VW or Audi is probably the way to go. They'll have Carplay/Auto/Mirror and that's what you want. The experience of an aftermarket stereo is just not great.
