I recall a number of years ago it took Toyota and VW about 37 hours to build a car. It then took VW about the same amount of time to QA the car and sort out all the issues, still to have a car less reliable than Toyota. Toyota had QA and the TQM, Lean etc principles sorted.
These figures are quite old ie several years and VW has no doubt moved on a lot more than Toyota in the intervening period. Bastid Germans (ie Checks) still managed to build me the wrong car just over a year ago, so they have so still have some basic sales order to manufacturing comms to be sorted.
Will be very interested to here from those with more up to date info.
