Hey, Bit of an odd one. I'm traveling through Frankfurt very soon and need to purchase a roof box. I've found the one I want and will need to get it installed (with the rack system). I have no tools and never been good at these things so I'm looking for a local garage In Frankfurt that can fit the rails and box. Installation should take 1hr max (according to the manuals) Can anyone recommend a garage in Frankfurt that will do this? Many thanks in advance.
