Grease Sucho is a mission in Grand Theft Auto: Liberty City Stories given to protagonist Toni Cipriani by his mother from her restaurant. The mission is unlocked after the completion of Big Rumble in Little China.
The mission begins again with Toni dropping by his mother's restaurant looking to impress her in order to win her respect. Toni, after entering a vehicle, drives to the start line outside of Portland Harbor. Toni, Sucho and two other drivers then race around Trenton, Chinatown, Red Light District, Hepburn Heights, Saint Mark's and Portland View. The race is a one lap race, and a short cut-scene then starts. The cut-scene is of Sucho driving up next to Toni, and then driving off. Toni gives chase, killing Sucho.
Toni Cipriani: Ma, I'm back.
Momma Cipriani: Look at you! You look so thin! If you were still living here with your mother, like a son should, you'd be eating right. And look at those cars you drive, you shame me Antonio! Really you do. People will think I brought you up wrong.
Toni Cipriani: Well what can I do Ma? You know I'd do anything for you.
Momma Cipriani: That Sucho boy is racing downtown today. If only you were more like him. He treats his mother with real respect. Of course, if you father was here he would win the race AND take the smug grin off that Sucho boys face! Yeah, he'd make him eat lead! Ah! Your father was a real man! Big balls!
$1,000 is given to Toni for completing the mission, and the mission Dead Meat is unlocked.
