There should not be a problem starting you 911 in the cold weather providing you are using the proper oil viscosity such as 0-40 for the colder ambient temperatures in your region. And a sound battery. As long as there is not any precipitation or snow on the ground I will drive my 911 or my twin turbo in the cold weather. You can also consider a dip stick heater on the 99 911. I know you guys have much colder weather then NY..
