Don't know if it applies to your car, but I was advised by my dealer that they are 'incompatible' with the sunroof I've ordered.
Can't quite see why myself as they seem to sit between the gutter and the doors, which is unchanged with the addition of the sunroof - unless the bars foul the roof when it opens... Good thing we're keeping my Mondeo Estate as a load lugger (although the missus will have to wave goodbye to her '98 punto sporting)
The Bravo at my local dealer has the roof bars fitted - if no-one has replied by the weekend, I may use this as a flimsy excuse to pop down and have another look!
