adnan ur right innitially i also took it a serious forum but later on i change my mind as members (it seems to me they r car dealers) start spoiling the add by commenting like "toooooooooooo high" or i sold car of same specs much lower then what ur asking for and then they contact u on mobile to get some thing at a price of "Yateemon ka Maal".
grading/rankin is good suggestion and will help us from avoiding non serious stuff.
