As a student you are paying your tuition fees, stationary items, books, photocopy notes, computer printouts, lunch money and what not. It is so much better to buy a second hand chinese motorcycle and sell it after you are done with your studies. You can use the motorcycle for commute and fun. There is also no need spending money to maintain or clean the bike as they cost Rs25,000 - Rs35,000 and after few years of use you can sell it again and not loose any money.
After you are done with your studies you can upgrade to GS-150 or CG-125 or even consider a brand new car.
