This is a popular misconception that is reinforced by the reality that there are a lot of hack body shops out there. I used to have to convince my customers that in fact a quality shop could very easily return a unibody car to original specs, often times better. All it takes is a commitment to doing the job right, and the right equipment.

Just to add emphasis to Darrel's comment, get the chassis straight before cutting anything, otherwise you're just chasing your tail.
