Can anyone help me with identify this Giant bike? I need a name for this bike so I can look into it. It's going to be sold to me but I don’t want to get ripped off. Thanks!
You should ask the seller for all the information you need about the bike, because a) they should know more than we do and b) if they can't give it to you readily then there is more risk that it is stolen. These things do happen!

Don't tell the seller this, but the name is usually written on the frame. If they can't manage that much then consider walking away.
