Completely agree with this. Appearance and what you will use it for are key. I ended up with the OEM rack- got a good price from the local dealership. I can only speak on the OEM rack- but it is really quick and simple to install.From my experience aside from the appearance of the roof rail systems, see what attachments you will be using or find yourself using in the future if possible.
Personally I found the OEM roof rails and crossbars very easy to install, although you won't be wanting to remove them once installed (At least not the rails anyway). The picture you attached is not the OEM roof rack, at least not here in the US.Any experience with the oem roof rack paired with Thule bike rack (fork support such as echelon 518) or similar?
How easy are the Mazda roof rack to install/remove from top of car? Do they require any modifications done to the roof mouldings?
