When Michael returns to snowy Tahoe and his big black car passes through the gate, the guard closes the gate with a big ADT Home Security logo visible.
The big black car is a real rarity: a '58 Chrysler Imperial Crown Ghia limo, one of <25 built by Ghia of Turin and, at ~$14k, the most expensive American car of that year. Anyone could have found a Cadillac limo of that era--trust FFC to use this rarity for six seconds in GFII.
BTW: If you look closely at the windshield of the red and black '58 Ford Custom 500 that Michael drives to his meeting with Roth in Miami, you'll see a Florida vehicle inspection sticker from the Seventies.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
