I like the idea, but you have no idea how hard it would be to manage that from our perspective
It takes me over an hour just to select and put up new cars each month, and that is just car, year, and name. Imagine if I had to manage articles, people coming back in 2 months asking to modify their article because they bought so and so modification, etc. It would be a logistical nightmare.
Good suggestion, and I have thought of it before, but in reality it's difficult.
