We have the Volvo roof rack and four Thule bike racks for our 960 wagon...
Two bikes can go on the roof of the car, two on the roof of our tent
trailer... If we made some bar extensions on the roof rack we could probably
squeeze all four onto one roof, but instead we got a hitch mounted rack as
well, for when we're not towing, but want more then 2 bikes.
This setup has been working well for the greater part of a decade, the only
downside is lifting the heavier bikes up that high... Small step ladder and
an extra person makes it go a little easier.
