1- Idled down to allow the turbo to spool down and even out the temperature in the turbo. The engine needs to be running to circulate the oil and coolant if you shut the engine down without idling the engine down it can burn the oil or coolant and in many cases both which will cause carbon blockages in the oil feed and coolant feed and hamper lubrication leading to catastrophic turbo failure.

2- Get a Turbo Timer, so the bearings in the Turbo don't seize (Refer to #1).

I feel very fortunate as I never heard any of this until I'd had my turbo for ten years. Then I started following above recommendation most of the time. I just kept my oil clean.

Example - if you needed to move my car in the drive way or some other quick thing...you had to start it, move it...let it run for a minute or two - and then shut it down. And even then sometimes it would be difficult to start.

Pain in the ***, oil burning, gas guzzling and no power. While I liked the exterior design and 4 doors alot - well, that's all I liked. Oh - it did handle well on the CA mountain roads once you got it going.

Our cars are FI V6 - bullet proof ancient engine design. Our engine is in many nissan/infintiti cars in many forms. Start it, turn it off, start it, turn it off. Never an issue.
This is what i was trying to say in my post exactly. Same issue.

This sounds like a reference to concerns over turbos; shutting down with red hot turbos can be bad.

Irrelevant for your NA car (or for turbos with proper oiling/cooling).

not really if you plan on driving it on a daily basis for more than 10miles at a time (180F oil temp, no steam coming out from exhaust).

in the winter time during hibernation i dont start my car cause i dont want moisture in my exhaust system.
