FYI, the highest talent you can get at 5 is 19, but I will scout for you people with the best health, speed, physical and talent, along with a bit of attacking and defending.
So man, they all seemed pretty pathetic to me, perhaps that is because I am about to hit level 9, but the best 2 seem to be http://igpmanager.com/play/?url=team-driver/518483 and http://igpmanager.com/play/?url=team-driver/551556 if you were willing to risk low talent, which bare in mind doesn't affect out-and-out pace until you get the other stats quite high, I would go for http://igpmanager.com/play/?url=team-driver/826 they are what I would personally go for (as a temporary driver until I would hit L7 where you get good 19 tal drivers and some 20) and also has the added bonus of being the 826th oldest driver in the game.
