I bet a trunk mount would be the cheapest. I would go that way especially if you aren't going to use a rack much. I know to add a hitch would have cost at least another $200 for me.

I have the roof mounts but I haven't used them yet. I transported a FS mtn bike in the back of the Forester because it was too heavy to get up and down off the top. Around here, I don't leave my car unattended for long with a bike on or inside.

Enjoy your new place.
