What it needs is a workforce that really has pride in what they do and many of these issues would be resolved. Perhaps a view that number of TMers would be horrified to hear having a rose tinted view of MMC. Before anyone shouts at me...I've spend a fair bit of time at the factory and and accept that I have a somewhat biased view of MMC and surprise myself with this view!
But you can't hide behind a "hand built" image....being hand built should mean that issues like rubbing cooling hoses, badly fitting carpets, poorly made bonnets etc should be resolved there and then.
