I am not quite sure how I would react to Nissan essentially telling me that, due to a quality control issue on their part, while every other buyer of a 370z gets an engine built by multi-million dollar machines in a controlled environment, I will now be getting an engine built by a UTI graduate in the back corner of a dealership. I certainly hope they plan on putting a fresh extended warranty on that engine.
edit: no offense to UTI grads.
I know a UTI grad who is a Mercedes master tech and he's doing better than I am!
