Quinny Buzz

I would like to know if a Graco car seat fits into the Quinny Buzz 3?

We bought a Graco car seat for our child, and now we have a friend offering a Quinny Buzz 3, but we're not sure if our car seat clicks in the same as the Maxi Cosi that is recommended to buy with it. we could just try it, except our friend doesn't have the special bar attachment needed to click in any carseat. I'm afraid to order the bar from Quinny only to realize it won't work anyway. Does anyone know? glennyf@hotmail.com
