Do these threads happen once a month or something?
Apparently yes.
I was positive there was a thread a couple of weeks ago that was originally started in the Mk7 section, then moved to Off-Topic. So maybe the OP of this thread hadn't seen outside of the Mk7 box and thought that it hadn't been done.
The title of this post is a bit misleading anyway, "History of Cars" makes it sound like some documentary about the history of cars, not a list of cars you have owned.
