I use a Saris Bones rack, I think it is great. It would work on any car. Just make sure to rest it on the BUMPER on the bottom and glass on the top. I wasn't thinking and rested it on the lower hatch and glass, now I have two nice large dents.
If you have a stock roof rack get the yakima forklift. It the the one that I found that fits the best with the stock roof rack. They have to be mounted backwards but I still like it.
I took the factory rack off my Vibe and mounted a Yakima rack -- for kayaks. I already had the hull stackers and cross bars. Frankly, wasn't thrilled with the way the clips attached and the setup worked. Dented the section above the door from over-tightening (my fault), but only because it came loose on me while on vacation. Not sure I would suggest this setup for kayaks....bikes may be just fine.
I use a trailer hitch and hitch mount bike rack. Does double duty for me because I also tow trailers and I use the rack on my van also.

I just added a Curt Class II hitch and a Yakima Stick-up bike rack to my 2009 vibe and I am really pleased with it. Installing the hitch was really easy and the stick-up holds both my cross-bike and my wife's step-though commuter which has fenders on it. Also holds kids bikes. Very versatile! The best part is that with my bike on the rack in the first position (closest to the rear bumper), the stick-up's tilt down feature allows me to fully open the hatch and access the trunk! It doesn't work with my wife's bike in the first position though - with her's there and it tilted down i can only open it halfway due to the wider handle bars. Also, with the rack in the upright position (no bikes loaded) you can't even see it out of the rear window so it doesn't obscure the rearview at all. Again, very pleased with this rack on my vibe!
