I don't think 20 year olds should be allowed to drive 430 HP cars.
Malibu is spot on. I bought my AA supercharged M3 at 20. 625hp and never came close to losing control of it, much less hitting a tree. All about driver ability, or, more importantly, the driver knowing his abilityHas nothing to do with age. Just has to do with how mature you are to know your limits and not to speed/drive like an idiot.
