I hope your wrong, they have done very well, I agree they have not nailedThey lose a vast amount of efficiency, not just through the assembly process but through almost the entire design of their vehicles, which are I'll suited to mass production and with unnecessarily complex structures (the inner wing stuck in my mind as a very graphic example, but little failures like that were repeated right through the design). Without redesigning the entire range and restructuring the assembly process they won't make ground on that, and neither of those are easily addressed.
They are losing ground, and will continue to do so, to manufacturers who understand cost control, quality control and mass production.
the manufacturing process in regard to time and costs, but they make a
very good product.
I understand the inefficient aspect, but other manufacturers go the other
way and use inferior components and cut at every opportunity, I like that
a lot less.
