Good question. First part is you have to buy from GM Fleet sales. I'm not sure what it takes to qualify. You might have to be a business.
That's why I'm going to become an ordained minister and hold church in my house once a week so I will no longer have to pay property taxes. Since it has been argued that atheism is a religion, my church will the Church of Modern Day Atheism.Probably easier to set yourself up as a religion and use it as a religious purpose vehicle. Then score no sales tax at the same time. With this, you'd have to be able to get an outside loan and carry in a check, I think or maybe they'd lend under certain conditions. But registration of a religion is waaayyyy easier with more benefits.
