Yup, looks bad. I needed to drop the subframe and then heat up the bolt bolt with a propane torch. Once heated, I used a good pair of vise grips and was able to remove the bolt.

The most difficult part of this procedure was getting the control arm bushing to release the bolt since the bolt was rusted solid to the bushing sleeve.

I had the same issues on my '05 vibe when I replaced the control arms, took an extra 6hrs and I ended up having to burn out the bushing and enlarge the subframe hole to fit the metal insert through. It was seized so bad I never got it unstuck. An impact was useless as the bushing dampened the impacts.

Now on any car I own I pull the control arm bolts and antiseize the whole thing so it never seized to the bushing sleeve. Takes some time but saves hours down the road

I also ended up burning part of the bushing while lowering the subframe.
I torched the bushing sleeve a number of times, so the heating and cooling process along with alot of hammering on the bushing sleeve helped to release it from the bolt.
