Am I to assume that having a multi with 2 sunroof's means that Roofbars are not an option?
Has anyone else come across this problem?

Nope. I had an '02 Elx and had roof bars, albeit aftermarket ones. They fitted fine AND the sunroofs opened without fouling them when they were loaded.

My ones fitted in the original Fiat mounts in the roof.

Did have some pics of it with the roof bars on but can't find them, sorry.

A guy round the corner from me has the twin sunroofs and original FIAT bars. Occasionally he fits a roof box onto them, so no problem.

Thule roof bars (which don't use the built-in mounting points) and Karrite (?) roof box fit mine perfectly, and again, both sunroofs will open too.

I bought a set from ebay last week which use the original fiat fixings for £40. Not bad quality for the money, bit fiddly to fit but fine for my use (picking up large sheets/wood from diy sheds.
I have not tested them out properly as I fitted the back bar last night to make sure they fit ok.
On the plastic trim which runs down the roof of the car there are small plastic cut outs which you press down and slide to one side so that you can remove them. You then put a small upside down T shaped metal piece into the hole in the roof fixing and twist it. You put a plastic lug in to keep it in place and then place the plastic foot on top of it and fix the roof bar fixing to the metal T piece using a bolt. The only thing I might change is maybe cut some rubber matting to fit under the plastic foot just in case it scratches the paint work.

We have the Fiat supplied roof bars.

Fiddly to fit but a good aesthetic design when in place - all smooth and nicely finished. Channels in each bar accept Thule type fixings for roof boxes and bike carriers etc (had to cannabalise several Thule packs to find the bits I needed to fit various bike carriers).

One word of caution - always tighten the fork carriers on mtb all the way - had mine jump off at Center Parcs and the bike made a mess of the door frame (since repaired).

I have the Automaxi roofbars, which cost about £45.00 from ebay. They are very solid items, and have large rubber feet which sit on the edge of the roof, adjacent to the rubber strip. It is then secured in place by a clamp that grips under the door shut area (same method as the Thule fitting).

One thing to watch is I originally bought the plastic ones from ebay(made in Italy by 'Cam'), and ended up sending them back, as they did not fit very well - it didn't matter how much I tightened the fixing bolt, the foot was still pretty loose on the roof, and I was able to easily swivel it around. They also made a horrific whistling noise at motorway speed, and within a couple of weeks of being fitted, and not yet having carried any load at all, they were starting to split quite badly on the big plastic block that forms the middle part of the foot pack.
