I've been playing the story mode for GTA V PC and as Michael, I came across an Infernus and started driving it around. I probably started a mission and got an alert that my Infernus was impounded.
Later, after forgetting about this, I drove past the impound lot and noticed the car symbol (white) inside. I payed the $250 and retrieved the Infernus. I read that a car has to be modded or bought to be impounded.
Is this supposed to happen? Will it continue to become impounded until I buy insurance for it?
