Installed these racks on my factory side rails and by themselves they look like a factory cross rails. Then I installed the Yakima FATCAT 6 Ski racks and it is a fabulous looking installation and really quiet. You can tilt the sunroof with the ski bindings up but if you carry the skis back to back you have to leave the sunroof untitled but can open it. Great combination that doesn't destroy the appearance of your X5. This is my 3rd setup from Rack Attack and will be back in the future.

The fit and finish of this product is fantastic, however, the s46 bars state they can extended to 50 inches. fully extended tip to tip they measure out at 47.5". So otherwise not being as long as advertised, and therefor not working. they otherwise look and mount great.

It depends on the car. If the other vehicle has the same style of factory mounting points (such as they both have raised rails), then as long as the bars are wide enough you should have no problem moving the rack between the two vehicles.
