You must do a complete inspection of the suspension, front and rear. Any and all mounts, bushings, and links must be in good shape, and a four wheel alignment is required on these cars, not just the fronts.

Bad strut mounts will drive you nuts, as they allow the steering inclination to change while driving. Check for cracks (they are the rubber thing at the top of the shock tower). If there are visible cracks or signs the retainer bar has been touching the outer mount, replace them and do another alignment.

You are probably due for rear links, too -- but check the rear subframe mounts. When these go bad, they allow the rear subframe to float around, usually causing the car to pull and be unstable.
