My thought about Nigel was that perhaps his absence was unplanned, given that his presence was so consistent throughout the second season. Maybe they were scrambling to restructure things quickly without him if he was not available for filming for some reason.

I'll gladly admit that's an incredible stretch! :-)

As for the Caddy, my original thought was the same as yours, that Nick had acquired it in his present life, perhaps to facilitate his need to interact with mortals so much. There is however the NYC driver's license from the '60s in the name of Nicholas Forrester which Schanke finds in the glove compartment in 'Close Call'. It's hard to argue that it could indicate that Nick owned the Caddy from the time it would have been a new car. Not that I believe that Nick would ever be that careless, or that sloppy, given how pristine the loft usually was, but it is canon.

I also agree that I could see Nick and Natalie very easily reflected in Nick's relationship with Katherine. It would have been a nicer--and probably more realistic way to end the series.
