You can do something that is close, but not the same.
What I have done is start a "build thread" or journal in the "General" subforum of my car model (in this case, the CX-9 General subforum). In that build thread I post updates about the car and I also include photos from time to time. Then I copied the link to that thread, and posted it in the "About you" section of my profile (click on username at the top of the page, then "Account Details").
The problem with this is that because it isn't more "upfront" (as it would be if there was a direct link under each user's avatar), you'd never know it existed unless you went to my profile page, then clicked on the About tab.
In the meantime, please feel free to start a conversation (PM) with fellow users to ask about their mods or to clarify information. Most of us are happy to help!
