I want to Buy a Bike for Myselves

I am getting bugged with my Scooter as it is giving me problems day in and day out. I have decided to Buy another vehicle. The Question is that whether i buy a new one or an old one.

I can't afford a new one at this point as i have some financial crunch.

If i go for an old one then i don't know if i would get a good one or not. I am not able to find time to hunt for some good old bike.

I do not know what will happen, i am spending Huge money on transport daily.
