I was once fortunate enough to have the tour at Bentley. Now that's an example of how to successfully integrate modern manufacturing methods with a hand built car, and get the best of both worlds, and avoid redundancies. 80%of the staff retrained.
The assembly process is, literally, assembly pron. The care that went into each car was phenomenal. 9 months from order to delivery. And one left lusting after a Bentley.. Even at £250,000 a pop.
