Impounded is a mission in GTA San Andreas, which is deleted before the game's release. The mission may takes place after the mission High Stakes, Low Rider, supposed to get a phone call from Cesar then Kendl suggested that he would invite CJ over to get to know him better.
You were supposed to get a reasonably nice car and drive it over to his house. Once there, Cesar was going to tune it up for CJ and socialize at the same time. However, the car gets towed before they can do anything so the boys head over to the Police Station to retrieve it from the Underground Impound Lot.
These are the unused script from the mission:
