Use this forum to post up all about your car. I suggest 1 thread per car. Use the first post in your thread to put up the pics and information. When this information changes use the Edit button to update the first post. All subsequent posts can be used for people asking questions, praising or slagging
I'll look into a way of linking signatures or avatars to the first post here too so people can find out about your car from clicking on your sig.
