my son has gone with me to the track since he was 6 mths old for a little while then momma comes and picks him up he jut turned 4 and a half this past week and whenever he drives during practice (he does not race yet) he always gets compliments and people just stare and watch him drive as its pretty awsome watching a 4 yr old drive a 1.8 buggy around a track altough he does not have throttle "control" in the air down perfect yet, he can drive the track very well infact. and I hope in a couple years he will be racing then i can just wrench on his stuff
