Been playing for awhile now, and I've noticed the glaring lack of side missions like Vigilante, Firefighter, Ambulance, etc. That grinds my gears a little, but I at least expected a chop shop-style "want list" of cars you must steal. This game is called "Grand Theft Auto" after all. Stealing cars is kind of the framework around which the series is built.
So: is there a quest line where you steal a list of cars? And if so, where is it? (Talking about single player here, not Online.)
Followup: if there is no such quest line, then what the hell?
