Personally, I enjoy these types of threads, but participation can be inconsistent due to the disparity in difficulty from one puzzle to the next. Post something too obscure, and only a handful of people are able to identify it. After a few of these, everyone else stops visiting the thread. Post something more easily identifiable, and the hardcore car nuts won't answer in an attempt to give everyone else a chance. Then the thread goes inactive until someone new wanders in. So let's try something new - we'll run two separate puzzles at the same time. And hey, if it doesn't work, I can always just merge this thread into the other and pretend this little experiment never happened. So Isobel's up. She can post a car in each thread if she likes and we'll go from there!
