Apple, oranges, and the right cart to carry them in. Come on, people. Let's start up the gray matter rev's a little, shall we?
The issue I see (and I'm biased), is:
the element of design spec.'s
+ undertanding of the design spec.'s by the owner/driver,
- the sales pitches and historical rhetoric of the vehicle.
= actual longevity and performance aspect of the motor.
(Yes, it's the 21st Century math system.)
Look. If you buy a vehicle that is built for daily road driving (with all the lovely leather trim - jeweled clocks in the dash - coffee cup holder - mascara mirrored sun visor - 17 different electronic vibrating seat adjustments

- matching supple leather trimmed door handles - ad nauseim) by a company with "A renowned history in the Racing World" - and you're willing to ignore the actual physical and mechanical realities of the vehicle - and go out on to the track in high G turns with buble-gum sticky tires, resting on the rev limiter squeezing every Nano-Kilo-Calorie for that extra .0000001 second at the timing lights, you'll blow her up. Duh!
What Dan A. might be eluding to is (and I can never figure out what those "air-head 911" driver are thinking), the 996 is a different vehicle mechanically than a GT-3. Uh, yea. That might be why they give it different nomenclature. However. The driver/owner may not recognize the significance of the inherent physical/mechanical differences - (Hey, its'a "Porch", Dude. World renowned auto racing legacy, Man.) - and try to drive a 996 like a GT-3. The result? Well.... let's just say "Your results may vary. Actual performance may be less than expected. Vehicles shown on closed courses with professional driver."
I really don't think you can carry any expectation of a vehicle's durability based on the history of a manufacturer alone. I would think you should look at each individual model, if not each individual
car and assess the capabilities separate from all the rest. Sure, some makers have a better percentage of endurance. But assuming
your particular vehicle will be bullet-proof is, I think, naive.
I think (and that's a stretch, I know) the issue is knowledge. Knowledge of the driver. Knowledge about the
true capabilities and limitations of the individual vehicle. Knowledge of what may be perceived or assumed rather than what is factual.
I'd guess this would be why this forum is so great

.
Just my musings.
