The office is about oh 3/4 of a mile down the street, with the stop lights and traffic it takes about 2 minutes. I never warm my cars up unless its really cold, if its 40 or over I just turn the key and go. But I do keep off the turbo until the oil has warmed up.
The 617 never protests, the 603 does. I do a lot of driving during the day, so I don't worry about the short trip.
The broker has used her SDL around town for well over 15 years and its still going strong. 200k+ around town short trip miles isn't enough to kill them it seems.
Thats the nice thing about 617's, the really don't mind short trips, never complain.
