@ Gautam:--> I'm sure the dealer had bad intentions. One cannot take advance for one product and then ask you to purchase another. Your friend can go the legal way, and get double the advance amount back, on charges of unfulfilled commitment.
This law is there, atleast for property dealings. Don't know exactly will it apply here or not, but it should.

@ Puneet1: Dude, we understand R125 may not come to India, but please read carefully the last 3 posts, from Synn to HydBiker's post.
I say R125 is one of the most overrated bikes. Synn bro is correct about RS125 - It's a 2 Stroke, and it deserves & gets more attention.
