Stevie has a garage called S&M Auto Sales located in Bohan, where the player delivers stolen cars in exchange for cash. Only the requested vehicles are accepted until all thirty car deliveries are complete; at that point, any car may be sold for cash. The reward is dependent on the model of the car, and its condition.
Brucie Kibbutz and Stevie are apparently friends and have had business dealings in the past, as it is Brucie that asks to borrow Stevie's gold Comet to race in the mission, "No. 1." Upon winning the race with Niko at the wheel, Brucie is so impressed that he turns the Comet over to Niko (implying that the car is not legitimately owned by Stevie, but is simply a "company car" obtained through his stolen car business). This incident is referenced twice more in the game: first, when Brucie calls Niko to inform him of Stevie's interest in employing him to steal cars, Niko asks if Stevie wants his car back, to which Brucie replies no; second, Stevie eventually states in a text message that he misses his Comet, and asks Niko to obtain another one that he has had his eye on: a plum-colored one parked in Westminster. Stevie's missions become available after completing the mission Smackdown for Derrick McReary.
At the end of the mission I'll Take Her, Gordon Sargent calls for a man named Stevie to take Gracie Ancelotti's pink Feltzer and destroy it. The man then comes out from a building behind them wearing a beige suit with a red tie, gets in the Feltzer and leaves. It is unknown if this is the same Stevie, however the association with stolen cars indicates that he may be. When the cutscene is over the man can be killed with no repercussions; this may indicate that it's not the same Stevie, or it may be an oversight. It is never again referenced in-game.
