There can be differing reasons as to why gearheads purchase ultra-expensive supercars. Some buy them purely to enjoy them for what they were designed to do; tear around roads and racetracks with the kind of pace that even Evel Knievel would think twice about. Others look at them more as investments, and thus do everything they can to preserve their value. This normally involves keeping them locked away in a hidden garage beneath a sheet to prevent damage to that expensive paintwork.The Porsche 911 997 GT2 is a great example of such a supercar that works well in both these approaches. It not only offers a blazing driving experience that'll leave you feeling gratified by the blessing of life, but also the chance of earning some juicy profit in the years to come. The 911 GT2 Is The Upgraded Version Of The Already-Rabid Turbo Porsche Porsche's 911 range is one of the most confusing in the automotive world, with the German marque offering various versions of the legendary nameplate that are all built to excel in different areas. The GT2 is one of the most fearsome of these special editions, given that it's the stripped-out and upgraded version of the 911 Turbo. The Turbo on its own is already a devastatingly quick machine, with the 997 generation model kicking out 430 horsepower courtesy of its twin-turbocharged flat-six powerplant.Feeling it was a little too safe, Porsche tasked its engineers with building one that would allow the full potential of that amazing engine to shine through. Although not too much, as that was the subsequent GT2 RS's job. Anyway, the 997 GT2 made its debut for the 2008 model year. The 911 GT2 Was A Track-Ready Monster Porsche It ended up being built over a span of five years, with the machine being carted off to retirement in 2012. It not only came with more grunt than the standard Turbo, but Porsche's zany technicians ripped out as much weight as they could get away with to ensure it was still usable on the road. This included ditching the Turbos' four-wheel drive system for a lighter rear-wheel drive configuration, as well as removing the rear seats. The 911 997 GT2 Is Worth A Fortune In 2026 Porsche Being the higher-performance and rarer version of the 997 Turbo, Porsche slapped a heightened price on the GT2. While the former had a base MSRP of just over $126,000, the GT2 demanded $191,700. While jolly expensive for a Porsche, the GT2 was the most powerful and fastest variant of the 911 ever built upon its launch, so it can be let off somewhat. Furthermore, interest in the vehicle has grown nicely in the past several years, to the point where it's worth around double what it was when new.Classic.com reports that the average used value of the 997 GT2 currently stands at $324,231, well over $100k up on the original MSRP. This number includes higher mileage and less well-looked-after specimens too, with cleaner cars getting ever more valuable as time ticks on. Tidy 997 GT2s Are Fetching North Of $400k Porsche In fact, values of the 997 GT2 are beginning to go through the roof, as evidenced by Classic.com. The site, which displays auction listings of the model from around the world, shows that the average used value of the GT2 in May 2025 stood at $263,000. A $60k increase in well under a year is not too shabby, and these increasing prices can be seen in the cars currently finding new owners.Take a white 2008 example as a good illustration of this. The 5,000-mile car was sold via Bring a Trailer in stunning condition, and eventually went under the hammer for $499,000. Plenty of other GT2s are going for a similar amount of money, with some even attracting just a little less despite having well north of 20,000 miles on the odometer, such as this black 2008 specimen sold directly through Classic.com. The 25,000-miler ended up changing hands for $429,000. The 997 GT2 Is Ultra Collectible Porsche The current price trend of the 997 GT2 suggests that it'll likely eclipse the half-a-million dollar mark before too long, and there are several reasons to believe why the sky's the limit for this wild Porsche. Firstly, they're damn rare, considering only 1,242 examples were ever constructed. Rarity is one of the key elements that helps push up a car's residual value, but there are other characteristics of the 997 GT2 that will push its used value to new heights in the coming years.It's much purer than the 'pure' models that Porsche is currently churning out. For one, the 997 GT2 can only be had with a traditional six-speed manual transmission, whereas the follow-up 991 GT2 is only available with a semi-automatic unit instead. This takes some of the old-school brutality and engagement away from the experience, a problem which is set to get worse with the future GT2. The new car will have the same hybrid propulsion setup as the 911 GTS-T Hybrid, which only adds weight and complexity to a car that simply doesn't need it, at least in the eyes of purists. The simple nature of the 997 GT2 makes it more appealing to collectors, as does the fact that nothing like it will probably be built by Porsche again. That said, in the interests of safety, perhaps this isn't a bad thing for some drivers. The 997 GT2 Is One Of The Scariest Supercars Ever Created Porsche A stripped-out, twin-turbocharged 911 that sends 530 hp to the rear wheels is about as scary as it sounds. While Porsche's engineers worked well to make the GT2 as balanced as possible, its rear-heavy 38/62 weight balance still means it'll snap if you get a little too aggressive with it. If you decide to explore its limits by switching off the traction control, you'll also find that spinning up the rears is a constant risk, an outcome that could prove dangerous when combined with the model's rear-heavy construction. Despite using large 325-width tires, the torque from the twin-turbocharged engine will quickly unstick them, so keeping the TC engaged is pretty much mandatory unless the road is bone dry. Even then, the GT2 will put its rear-mounted rubber through its paces.The fact that it's a good 300 pounds lighter than the Turbo further feeds into this, as the extra responsiveness means it can feel more twitchy for less experienced drivers. The ultra-stiff chassis enhances this characteristic even further. It's certainly not one for the faint of heart, and demands precision and concentration to get the most from, otherwise it'll let you know about it. Once you finally feel confident enough to let it run, you'll find that you'll be blasting past the 60 mph threshold in 3.4 seconds.On second thought, maybe keeping it fed and watered in a garage would be the safer option. You could at least sell it for enough for a good therapist, which you'll need if you decide to flick the TC off.
