Okay, thanks for the info.
I mean, I'm not too picky as long as they look cool so, I'm pretty sure I'll find something interesting for purchase and now you mention it, it's true that the most recent gameplay trailer strongly suggests that you can buy vehicles.
There was a whole night city wire dedicated for cars I believe it was the 4th Night City Wire
Regardless.
You can steal parked cars by investing into netrunning or commondeer occupied cars by investing in strength to yank them out of the cars. Mind, some people might be more stronger than you so they can **** you up when you try to steal their cars.
Also, the cars that are stolen cannot be stored in a garage otherwise cars that you earn or buy ( and they can be pretty expensive ) you'll be able to store in your garage and summon them much like you summoned Roach in Witcher.
Also it was stated how the player purchased cars drive/sound/look different to the ones you see on the street of the same car.
There are also different states to cars, naturally, you can't find a rusty high-end car but you will be able to find more common cars different from one another. Nomads that live outside the city in the desert have their cars often tuned to fit the harsh deserts of the badlands, while some are rusty and busted up and some are more sporty/brand new and it also reflects in the car's handling, outlook, sound both from exterior and interior.
Lets just stress the fact that they have put more work into cars than some racing games. And its not a racing game. ( It does have races though! )
