need a roof rack to attach thule 857 caravan luggage bag to

[thegoodlife]

I have a Thule 857 Caravan luggage bag that I used previously on a Subaru Forester. I used to attach it directly to the Subaru Forester factory rack. I've since traded in that car for a 2004 Hyundai Elantra that currently has no car rack on it. What do I need to use for some kind of roof rack with crossbars to attach the luggage bag to?

You'll want to get the Thule 400Xt Aero roof rack system. This is a general purpose car rack that includes the pair of crossbars you can then attach the Thule luggage bag to. You'll want to be sure to get the Thule 101 Fit Kit clips which are made to go on the 2004 Hyundai Elantra. The other components included with this roof rack are a set of 4 Feet (towers) and a pair of cross bars (the 50" length bars are the length you'll want for the Hyundai Elantra.
