caropractor
A highly-skilled worker at an auto-body shop who specializes in performing front-end alignments, straightening out frames and panels, and generally aiding in restoring the correct positioning of bent/warped vehicle-parts.
Off-roading enthusiast: My 4X4 got kinda bent outta shape after doing the 100km Baja slalom, so I hadda take her to a caropractor to get her runnin' smooth and straight again.
