I hope anyone considering this is comfortable with the fact that they'd 
be spewing lead into the atmosphere. Maybe you don't know any children...

Seriously, I have to protest this kind of thinking. Given what we know 
now, there is no excuse for using leaded fuel, any more than there is for 
using asbestos in classroom insulation. And there is no performance 
rationale for using 104 octane fuel in a street MG, anyway, except for 
ego gratification. I mean, get real -- who is running 12:1 compression?
