Hope you get these issues resolved quickly to your satisfaction Blake.
Your comparisons with the Beamer are very even handed I thought and you are prepared for the "incoming". There is a prevailing "Emporers New Clothes" nucleus around that seems to think that "shoddy" workmanship is totally acceptable in a handbuilt vehicle but don't like to say. I personally think it's an excuse, if Aston Martin engines are still handbuilt I bet their failure rate isn't too high.
Enjoy your (s)miles
