Auto Shows?

I live in Chicago, and with the Chicago Auto Show starting tomorrow, I had a thought. Would it be possible to implement Auto Shows into the game? It could be something simple - you pick the show you want to attend, you choose how much space you are going to rent, which cars to put there and maybe which car to put the emphasis on or maybe do the unveiling of the new model, and after that, depending on how much money you invested into the show, your sales will grow in that region for a year. And then, if you keep going big every year, but then suddenly decide to lower your investment in the show, your sales will slightly drop. It shouldn't be a big percentage either up or down, but it would be an interesting addition.
