None, in the past 10 years or so I have been buying parts from Roush, Saleen, Shelby etc. on their take off parts. When I go to pickup these parts we usually pay cash. Carrying 30-40K in my pocket makes me nervous. Indiana CCW was not honored in alot of states I would travel to including Ohio. I went to Utah and took a 8 hour CCW course and was certified. This covered 75% of states I did transactions in. Since then alot of states including Ohio dropped those requirements and accepted Indianas. With CCW dropped here I don't know how all the works now.
