Dan Sucho is a character in the Grand Theft Auto series who appeared as a minor character in Grand Theft Auto: Liberty City Stories. Dan Sucho is a known street racer, whom Ma Cipriani admires, in so far as respecting his mother. Ma Cipriani tells her son Toni that if his father were still alive, he would beat Sucho in the race and kill him. Toni, looking to impress his mother, beats him in a race and then kills him afterwards. Ma Cipriani only referred to Dan Sucho by his last name, although his tombstone at the Liberty City Cemetery reads Dan Sucho.
In the LCS's files (viewed only by a file viewer), his name/file is spelled "zuko". This is because he appears to be inspired in the character Danny Zuko (played by John Travolta) from the film Grease. In the film, Danny also has a hot-rod car named Greased Lightning, which might be the inspiration for the Thunder-Rodd, a vehicle that Sucho owns.
