No worries - the group puzzles are a gold-mine, and quite a few puzzles have been sourced from previous group puzzles, and are not generallly considered re-posts.
My previous comment was for the people who looked at the puzzle, but didn't solve it. This site has TON of car photos and information. I hope all of our members spend some time in the solved puzzles section, which features thousands of cars, from ordinary to unique.
