The Aja Mahiya song is based in the time period of the year 1993 (bombay riots) a nd before.. As we watch the scene, where Amaan (Hrithik Roshan) is standing in the middle of traffic, we see lots of cars going by him.. Out of these cars, there is Opel Astra, and even Honda City.. If i am not wrong, these cars came in 1996-1999.. so the cars don't belong there...

The 'Aja Mahiya' song is based in the time period of the year 1993 (bombay riots). Later in the song, Hrithik Roshan and the actress sing in front of a billboard. hat billboard was for Colgate Gel, which apparently didn't come around until 1996.
