I honestly wouldn't mind letting people I know drive my car, but none of my family or friends that I see on a regular can drive a stick. I have a friend in Cali who drives a 350, and I considered letting him drive my car when he was in town right after I bought it. But then I remembered that every single one of his cars has met a horrible demise. (Mostly not his fault, just bad luck. In fact his 350 was just "totaled, then un-totaled" by an insurance company after someone rear ended him. Bizarre story.)
I've had my car for a year and a half and so far the only people other than me who have driven it are service people. I'd never let a valet drive it if I didn't have to, especially since I know people who used to valet, and I've been told some of the shtuff they do with other people's cars.
