Cold weather? Let it run until the heat is nice. Hot weather get in and go but keep it under 3000 Rpms. No reason to wait.
very minimal - get in and go
5-30 seconds - Let the engine drop to normal idle
A minute or so - set up the radio/GPS
A few minutes - turn the car on and walk back inside
I've got underground parking, so the temp is usually around 15C regardless of outside conditions.
I usually give it 10 seconds, basically long enough to get my belt on and the handbrake off (old habits die hard), and a few seconds to listen to the engine for anything unusual.
I remember an old factory Porsche manual i had that specifically stated to NOT warm up your vehicle before driving. It basically said drive easy until at operating temperature. If i remember correctly it mentioned " hot spots" if you try to warm the car up before driving it.
Accent: 15-40 seconds or so with cold engine; maybe 8-15 seconds after warm restart.
XJ-S: 4 minutes with cold engine(turn battery on which resets trip computer- start and wait until it hits 4 min).

Start the car and get myself set up. Valentine1, heated seats, and go. Total time maybe 15 seconds. Unless its below freezing, then I'll give it a good minute or two to get warmed up a little. And always keep the rpms below 2500 until the temperature is normal.

Start car. Plug in iPod. Select song. Put up parking pass (so i dont forget once im in the school parking lot). put on seatbelt. Drive. So maximum 20-30 seconds
Regardless of weather.
Doesnt the engine warm up a LOT faster anyways when youre driving, versus when its just sitting there idling?
