Duramax, warm up time
I'm considering a 2015 Duramax that a friend is selling that is pristine and well maintained. He drives a lot, it already has 115,000 miles on it. I on the other hand have a short commute only 6 m...

I'll agree in general with the no more than 30 seconds warmup. Under reasonable weather. However at least some of the newer diesels WILL warm up when cold with a short idle time. My 2015 duramax with temps near 10F will start nice hot air to the cabin in 5 minutes from a cold start while idling. How?? well, one they bump the idle speed to around 1000rpm, second they run the turbo vanes to maximum backpressure. now the engine isn't just a air pump, it is actually needing to do some work. So, normally get in start and drive. when below about 20F I hit the remote start, let it run the 5 minutes or so it will do with the remote start, then get in and go. Oh, BTW GM is nice enough to also have the heated seats on while it is under remote start.
Wonderfull.
You'll get nice warm air in 5 minutes if you take off after starting also. Probably sooner since the load under way with moderate acceleration is still likely far more than the jury rig system the manufacturer uses to force the engine temps up... plus you are actually making headway towards your destination.
