Well after looking at this one website I went here to see if there was a section so that the members can set-up their own group buys. I don't see anything for this so I suggest that it is put into place. I would like to see one for the evo and one for the lancer (and maybe one for items that both types of cars can use).

 

Usually they just post them under which ever car that it relates to....

 

eh, I think there should still be a specific section to see if the "people" can get something together instead of relying on the vendors to have too much supply to then sell things cheaper and call it a "group buy" or "discount"
