Looking for a roof box for my 07 hyundai santa fe.It has the standard two bars going accross the top of the car. Would i also require roof bars or does whats on it currently(bought it new) sufice for a roof bar? When i google for roof bars for the sanat fe , it only seems to have them for the 00-06 model which i'm hoping suggests that the 07 model onwards doesn't need bars????
