i try to warm up the car a minute or two until the temp guage hits the second notch or so, sometimes (read usually) i am late for class and start the car and go...
on the m3 i start up, wait 30seconds toa minute until the rough idle dies down, and drive conservatively and not at WOT for 15-20 minutes(i'm rarely on the road fro more than 10 minutes so there's really not that much point for me) but that's hwat i do. for the benz i don't give a crap, i start up, wait 15-30 seconds, drive conservatively(relatively) and yeah

I just start and go.
You don't want to idle and warm up your car that way because most engines have hard time getting oil to the parts like that. You want to drive your car easy for the first 5 minutes or so until all the components are nicely warmed, then you can start to pick up the throttle. I think this is what most mechanics will tell you, unless you talk to a race car mechanics because they tell the driver to sit in the car and rev the engine for a good 5 minutes or so. I've seen this done by almost every team in CART, but then again, they don't have the luxury to warm up the car by driving slowly around the track before the qualifying session.
Yea, for sure don't idle longer than necessary. You probably don't need to idle at all, actually. Trouble is that oil pressure is at its lowest at idle and you'll be wearing engine parts fastest that way. Notice that in your manual it probably defines long periods of idling as "harsh" (or similar term) conditions meritorious of more frequent oil changes.
Mechanics worth their salt will suggest that you just drive very easy for the first few minutes 'till the engine warms up.
In some countries (European) it is illegal to leave your car idling to warm up. If the IS has an oil gauge notice that oil pressure is at its lowest at idle.
The M5 has a red (yellow?) line on the tach that gets higher and higher as the car warms up from a cold start. Hey, you can always run Slik50 or similar protectant if you're worried about longevity. As if any of us will still be driving our cars after say 50,000 miles, anyways!
Then again, 'other' Acura TL owners unlike myself might suggest that you rev the IS300 up to redline for a minute right after you start it up. That would be an easy way to reduce your compression ratio for a future turbo install...

I am just using that as kind of a rough estimate. I guess I should have stated that before, thanks for the correction.
Just drive the car for a few miles, especially on these N/A cars. For my old eclipse GSX, the engine heats up right away thanks to the turbo.
