Roof Top Bike Rack For 2007 Rx 350

[Loukewarm]

Looking for any advice in regards to roof top bike racks using existing factory roof rails and cross bars.

I can't help you with a roof bike rack recommendation but I can tell you that, after using only roof bike racks (Prealpina and Yakama) from the 70's until 1990, I would never go back to one after using hitch mounted bike racks the past 23 years.

I'm sure that roof bike racks have their positive points - I just can't think of any.
