Re: Car roof bike carriers..
Have a look at the roof box company, www.roofbox.co.uk their website is very informative and they sell spares too.
FWIW, we have Thule 591 racks now and they're great, you can hold the bike with one hand and operate the locking mechanism with the other.
Never tried the Mont Blanc racks but I would just say that the wheel mounts on the Thule 591 slide along which is very handy if you have various bikes with different wheel/frame sizes.
