No M6 but I'll let any of my friends drive my vehicles. If they didn't have the integrity to take responsability for anything that might happen they wouldn't be friends of mine. I let a friend take my 4 day old Jeep for a weekend when we ran into complications swapping motors in his Saab. In reallity, they're just pieces of machinery. Yes, my Jeep is more important to me than was my SPG or my 6 will be.
