This guy is selling a pirated version. I asked if it was real, he said it was real just not purchased on GM website. So basically he is selling a pirated copy for 100 bucks that I can go buy on ebay for $30 bucks.
I would double check that the $30 version is v2016 as the best price I've confirmed for the latest release is $99 shipping included.
