Well although older car doesn’t have subscription & sometimes break the emition regulation at least i can repair & modified it by my self, all i need is OBD & some skill tho
In the end I don’t need to worry about subscription, because it doesn’t have it at all plus I don’t need to worry about SOFTWARE UPDATES THAT CAN BREAK CAR, as long as you have gas & your car engine is healthy enough it can run no matter what
