911 history and ownership is a complicated little sub culture that takes some getting used to.
One thing I have noticed is how gearbox technology has moved on and how we now just take it for granted. The 915 gearbox which predates the G50 can be rewarding and as sweet as a nut to use, but you have to get used to it and work with it or it shows its displeasure.
The Porsche subculture makes the Morgan one look simple!

Furthermore, it is both easier to buy a dud and equally more challenging to understand why one model, which looks almost identical to another of the same era, is priced completely differently. Nuances such as MFI 2.7 and 3.0 non-turbo have become collectable because of other halo models, where they were once ignored/lumped in with the other models of the era. It is both fascinating and a potential minefield; easy to overspend and 'under buy', with plenty of painted-pigs thrown into the mix.
As for the 915, it can be a stunning box and when warm an absolute pleasure to drive. However, as you've alluded to, it can also be a little like the rest of the car, ready to punish you if you take liberties and drive without care and attention.
