The rule of thumb is that it takes 30 man-hours to build a car.
You've bought off on some bad propaganda, usually your posts make sense but you are way off here pal.
PS: I am not defending unions but only using this for comparison. Non union built cars ar in the 6-7% labor range.
Your numbers are BS propaganda. I take it we have ourselves on FR one of those UAW socialists.
30 man-hours to build a car?
30 man-hours for final assembly, perhaps, but a heck of a lot more putting together all the components - engine, transmission, suspension, interior, and so on.
