At one time PBS had a similar show in the 80's early 90's. I think the Discovery Channel bought the rights to it, but never made anything of it until 3 years ago. They only used the program as a time filler late at night or on a Sunday afternoon.
I work in an auto plant and Im still amazed at what we do and how its done. I see it everyday and still say WOW! Although the repition gets a little old at times, but the line doesnt stop. 43 seconds to put a dash into a car. 21 seconds to install the a door. .23 seconds to install a steering column. 38 seconds to install a seat. 14 seconds to install certain interior trim. Anywhere from 48 to 64 jobs per hour. Yes, 1 completed car every minute. One of the hardest and most dangerous jobs is to put the 2 gallons of gas in the tank. You gotta get it right in 14 seconds!

In the part where they say most parts come to the line worker already assembled, the parts are assembled on a sub-assembly line.
