+1 for the Atera Strada.
Atera actually make the roof bars and roof carriers for Skoda, Seat, VW, Audi, BMW & Mini (except you pay twice as much for the car manufacturers badge if you buy the stuff from a dealer from the dealer).
I bought a Strada for my wife’s car after putting a removable tow bar on it and also bought some roof rails, roof top bike carriers and a roof box for our trips to France with 5 bikes and a tent. What can I say.. I breed, cycle and travel !
I recently bought a Mini Countryman and I bought the Mini roof rails because I can use the same roof top bike carriers I bought for the wife’s car. The rear carrier for I got for the Mini is just a Strada with a special fitting to screw it into the bumper as opposed to putting on a tow bar. I can actually get 5 MTB’s on the Mini now !
Westfalia also make all the tow bars for all the VW group of cars. Order one with a new car and you’ll pay £300 more than you would if you buy one after picking up a car up. The removable one I had fitted even fits in a foam cut out in the boot with the car jack etc !
