This is a good question,
I think the reason why there isn't that many replies on this forum is like any other forum or profession.....u have the guys that are interested: the guys that read the posts, the guys that have done things with there car: creating posts, and the guys that know everything about the 370Z cause they've done it all: they guys replying to all the posts.
I ask questions on this forum, i create posts on this forum, & if I've experienced something with my Z, i reply to other posts. Majority of people that search this forum or any other specific forum, is to get help or ideas for their Z. Can't really put down any member if they don't feel the need to post a reply or create a post....
This is a great forum for info & ideas, and its all because of the members.
Maybe we should say thanks to all the members that have shared their experience and knowledge about the 370Z on the forum instead of wondering where them at.....
