I searched the puzzles solved from february to mid-march and couldn't find no brown car that matched.
My search was quite boring, I must say, yet brought up a few gems. I was amazed by the huge number of cars that I had never seen pass on the forum.
Otto's project of "Solved Puzzle Compendium" will never be completed, no wonder. Don't even think of it, Otto, you'll loose your health.
This search was made quite hazardous by the fact that, if I had to search between two dates, I came across puzzles solved much sooner than this, but updated by a more recent post. And I might miss puzzles solved in the right period, but showing in more recent pages of the board by a comment posted last week. If you see what I mean.
