I guess I'm biased, 'cause I have the Thule rack system for 2 cars.
I checked out

http://www.thuleracks.com/bike_products.html

and

http://www.actionsportsct.com/thule5.htm

and it looks like #589 and #545 would work out pretty well.  The
Thule bars I have extend out to the sides (can't remember the length,
but the bars are model #300), so my guess is that the above bike
fixtures might fit along the outside.

For me the placement doesn't matter, 'cause we have a GL.  :-)
