Depending how badly bent the fork is, straightening is not difficult. In addition, generic replacement forks are readily available.
A bent main frame, damage is often first seen on the top tube and down tube, near the head tube. You will see a ripple on the underside of both tubes, and the paint will be chipped or cracked. The ripple can be felt with your fingers. Of course, more extensive damage will be more obvious.
Simple test I use to spot a bent fork. Once you get an eye for it, it is very easy to spot a front to back bent fork. We routinely call out bent fforks over on the C & V forum (you can mentally draw a line just like my straight edge below and see many bends):
Bike in work stand:
Then use a straight edge (a yard stick works fine), centered on the stem bolt, through the center of the head tube, and through the center of the fork crown. If the fork is bent backwards, the fork blades will appear behind the straight edge. Of course, this does nothing for a side to side bend.
