This promo video from a collision-repair equipment manufacturer just happens to feature a 280ZX for the initial demo sequence.  The ZX has structural damage to the left-front and panel damage to the left rear.  The video offers an interesting perspective on how our cars' structures respond to this kind of straightening operation.  Everything you see here was probably done on a hurry-up basis and strictly by eye, so as to focus on demonstrating how the equipment works rather than the niceties of procedural details.  Or, at least, I hope that's the case!

 

And now that you've seen 'The Might Duke' in action, have a look at this video promoting what I'm going to guess is state-of-the-art for contemporary, high-end collision repair systems.  Pretty cool stuff, featuring a, 'Infiniti' 3D laser measurement/alignment system working in conjunction with x-y-z adjustable support pedestals.  The rack is sold under the 'Car Bench' brand name.  The pull-arm system is sold under the 'Piranha' brand name.
