May have been the Hotel's "VIP" limo. For that matter, the '58 Ghia Imperial may have been a de luxe airport limo for Michael, not his own ride. He may have had more modest tastes. For example: The car that Kay tries to go shopping in, and was stopped at the gate to the Tahoe compound, was a '57 Buick Special wagon (note the plain-Jane interior), a far cry from the higher end Roadmaster wagon. The rental car that Michael drove to Roth's house was a low-end '58 Ford Custom 500.
For this car buff, GFII is paradise for Fifties classics.
Yes it is. The only other Cadillac limo we see,that might be connected with Mike, could be the 56 Cadillac limo parked outside of the Washington Hotel. With its custom rear window, it appear to be a Derham custom.
