In the movie "3 Idiots," Chatur (played by Omi Vaidya) doesn't actually drive a specific car. He boasts about driving a
"Mercedes-Benz" throughout the film, but he never actually shows or drives one.
This is part of his character, emphasizing his materialistic and status-driven personality. He often uses exaggerated claims to impress others, which ultimately backfires in the end.
