He's not giving away the AK-47's right when you buy the car, he's giving a voucher for a gun at a local gun dealer.
You still have to go through the necessary paperwork to get it.
He knew using an AK-47 in his promotion would pi** off the news media and they would cover his story.
So far it seems to be working.
I still haven't seen whether it boosted his sales though.
