I did not pick up the roof rail when I ordered my car. Was wondering if you guys kno any aftermarket ones I can put on?

 

eTrailer.com lists some Thule ones that work. You have to buy separately: mount points, cross bars, and mount points's "feet" adapters that fit on your car. THey'll show you all of them. I came to about $500 when I looked.

Plus a tray, if you want that.

A hitch would up being cheaper for me, plus I still have a trailer to pull, unless that ever dies. But a cargo tray that is hitch mounted is still cheaper than roof racks plus tray.
