this is what i did. off craigslist, you could do this for ±$100.
Here's what you need:
qty~4
"raingutter" style yakima towers.
or 2 raingutters & 2
"highrise raingutters".
qty~2 58" cross bars.
qty~ however many
mounts you want. I have steelheads, but if you go with one that doesn't require removing the bike's front wheel, you might want the 2 highrise towers in the back or else the bike looks like it's riding up a severe slope. More importantly, you'll have to remove the bike if you want to access the trunk if you don't get the steelheads.
Mounting is directly on the back trunk lid, and is a bit of a pain. I scratched my paint a little
. It'll be heavy for the springs or shocks and you'll need a prop to help the springs keep the trunklid up, but I'm really happy with mine.

Oh, and get locks for the mounts. I think it's a waste to buy locks for the towers also, but you DEFINITLY need locks for the bikes. pfb
