Roberto- Dozens of Ferrari owners, V12s and V8s, with properly operating cooling systems, see variations in water temperature depending on whether she is moving or not and dependent on outside temperature. Mine has no warm-up problems and neither did most of those who have answered this question in the past. Yours obviously had a problem if the thermostat was not closing. Ferrari fits 70 C thermostats at the factory, and this is part of the reason the changes in water temperature are seen. As long as oil temperature comes up relatively quickly, the lower water temperatures should not be an issue. Water temperature comes up quickly any time she is stopped, and that is normal, too, as airflow stops until the fans actuate.
Many US cars were fitted with 160 degree F thermostats, too, which works out to 71 C.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
