I would be loathe to hand the keys to my brand-new 6MT to a teenage valet. When I bought the thing, they had to send a different sales guy for the car because the first one couldn't drive it.
I get that people don't want to bother with it, particularly in traffic, but I love driving my car and find it keeps me more alert in stop-and-go. Finding a new one this go-round was a nightmare as so few manufacturers still offer them in anything decent.
