Same here for the 08, if anyone knows... I talked to Yakama, and from what I understand they have a Roof Rack for the 03-07(?) but they DON'T have anything for the 08 because the trim or weatherstripping changed some how so their Support Towers dont fit anymore. This is a real bumber because I already own the Yakama Snowboard attachment that I had for my previous car.
I havnt talked to Thule, They may have something, but I remember Thule being a bit more expensive. I'd Try Yakama first.
