What I see in PW is spottings, modification info, buy/sell parts/ civic vs corolla.
Why dont make some sort of FYI section in which put all the stages of modification into it. List the parts one can install, interior, exterior parts, their prices (obviously they can change but one can out estimated prices).
Then there can be alist of FAQ's HOW TO INSTALL a part... e.g air filter or changing Engine oil.
I know that will be available in DIY section, but search option of Pakwheels........... i must say is soooooo..... aho !! You know what i mean....
I mean just create multiple sections for all the topics which are being discussed on daily basis so that people can talk about something else...
Secondly, I must say there should be magazine of Pakwheels, everymonth or atleast once in 2/3 months...
Thirdly, we have so many brialliant brains in Pakwheels (MashAllah) that sponsors can finance the project and brainiancs can use their head and resources to complete a 'pimp your ride' project, sell the car and earn money...
Or some other idea in which people can earn money with 'no profit no loss' for pakwheels...
