Recommendations for 2015 Q7 (running board and roof rack)
 

Can the Audi brethren provide recommendations to purchase below items for my 2015 Q7:
(1) Running boards
(2) Roof rack / Luggage rack

I don't want to burn my wallet, but don't want cheap stuff either :)
Recommendations most welcome!

P.S: I need a running board so that it is easy for my pregnant wife to climb in and out of the vehicle.

Thank you in advance.
