What matters most to you if you were buying a used 992?

What qualifies as a short trip, and why are short trips REALLY bad for the car? I drive my C2S to and from work everyday, 3.6 miles one way, and it takes about 15 minutes. The car gets up over 180 deg. F on every drive.
Living in an urban environment without a long commute, this car is either going to be a daily driver with trips of this length as a part of the car's life, or it will not be a daily driver. Not every car can be daily driven for miles on backroads every time it's used.

Short trips per say aren't what's bad, it's that the car spends a lot of it's time running cold which is where most of the wear happens. At least that's the 'wisdom'; there's been so much advance in oils and metallurgy over the last couple of decades I'd defer to someone who really knows that stuff.
I get it: Longer drives are generally better than shorter drives, and I love taking lengthy jaunts on backroads when time is available. But it is definitely not always the case, at least for me.

The 911 is often touted as one of the most usable, daily-drivable sports cars available. If that is really the case, it better be able to handle shorter drives around town doing the things that people do with their daily driver vehicles: Drive to/from work, run to the grocery store, drop the kid(s) off at practice, going out for dinner, and whatever other errands/events may compile someone to travel around town for relatively short periods of time. If it is not ok to use a modern 911 in such a manner, the car stays in the garage and will be a lower mileage example.

I think short trips or shorter drives are the sort that are less than 5 minutes, or short enough where the engine does not reach normal operating temperature, i.e. oil temperature around 220F (or ~105C), a bit lower if in sport mode at 212F (~100C).
There is nothing a modern 992 911 can't do in terms of daily duties and driving, but like any ICE car (a 911 or anything else), the engine needs to reach its operating temp to avoid negative effects down the road (no pun intended).

Even on hot days, my car takes a good 15 minutes to reach an oil temperature of 212 degrees. In the winter, I'm expecting that time to extend to about 25 minutes. I'm trying to use my car for longer trips to comply with the admonition that short trips are bad for the engine, but in real life, that is a hard thing to do consistently.

Are those 15 minutes driving down hill, in neutral, with a stiff backwind?
