I had a 997.1 GT3 comfort for the past year, now returned to a regular 911.
They're worth what the market says and much of it due to diminishing numbers of good examples, with the uprated components, many are invisible, but the drivetrain and steering stand out. Ultimately I think their greatness comes from the sum of their parts.
Im a pretty normal Porsche enthusiast (I think) and definitely felt the privilege of owning and driving an iconic version of an icon and much of its value was justified to me through that. I inevitably learned though, that I was hardly ever in a position to lean on the chassis enough, retard energy hard enough or unleash energy hard enough to put the car into the zone it was designed for. You can sporadically on the road, but for the rest of the time each of us will feel differently about the compromises.
You find out how far you're using one outside its zone when you get it on a track, preferably with some instruction to get you going if you're not experienced. Then it all makes sense, everything works in harmony and you find you are quite quick, but it may not be you, it could be the car :wink:
My use was urban roads, occasional road tour and couple of track days. I don't regret having one and wouldn't discount one again in future and if your use involves spending a decent amount of time using the car for what it was designed, it is an awesome prospect.
If its not, then its still fantastic if you're comfortable with why you have one IMO. Could be investment if you buy well, could be that getting the engine into the higher reaches of its revs range once a month is enough, could be just because you can, could be to scratch an itch, each to their own :thumb:
