hope this is the right section!!!

hi, i am on the verge of buying an audi a3, it is a 3 door model on a 54 plate.
now my question is this, can you get roof-bars to fit these so that i can put on my roof-box?
im not sure as there are no roof-rails and as it isnt 5 door, i dont see how you could attach the roof-bars!!!

any help or info would be much appreciated,
thanx,
marty

 

Im using Audi OEM roof base bars and bike rack made by Thule. My sportback did not have the factory rails. Im sure theres an application for 2dr A3s (?)
