i think i read somewhere you want to give it like 30seconds before you move. i could be wrong. i just fire up the car, buckle up, set my tunes and by that time it's like 30seconds past.

then no hard acceleration until water temp is nominal temp range.
for my dd (honda fit), i just start and go even in 0F. by the time car is fired up, my clutch is engaged and im off. i just drive real easy until water temp is normal.
