Strange, yes. But regretfully, mine seems to have gone from "perfect to BOOM". It was more of a "clang-clang" to be exact. Sounded as though some large metal object fell and hit the street. There wasn't anything down there, but the tech told me that a rod shot right through the engine.

He specifically said it was due to a bad "rod bearing". Again, I don't know exact production numbers, but I would be willing to guess that based on what I have found (or not found!), these problems seem to be just a "luck of the draw" kind of thing. I have full confidence that the car is otherwise just fine, and now even better w/ a new motor.

They really didn't have to let me into their restricted area to see the car "in surgery", and as an enthusiast (I have some other, fun rides that can be viewed by clicking on the "back to tale of..." then click on "sets" in my original link, above) and a customer, I was really impressed.
