The REAL Cost of Owning a McLaren, AMG GT-R, or 911 Turbo in 2025
Supercars look incredible on Instagram.
The reality? In 2025, the ownership costs will humble you fast if you’re not prepared.
Whether you’re eyeing a McLaren, an AMG GT-R, or a Porsche 911 Turbo, this is the real breakdown of what it costs to own one — not just buy one.
Most people won’t tell you this. I will.
The Cars We’re Comparing
To keep things realistic, I’m basing everything on real 2025 pricing and actual owner data.
McLaren 570S / 600LT (2020–2022)
Average market price in 2025: $150,000–$230,000
Mercedes-AMG GT-R (2019–2021)
Average market price in 2025: $145,000–$190,000
Porsche 911 Turbo / Turbo S (2020–2024)
Average market price in 2025: $190,000–$260,000
These three are some of the most cross-shopped modern supercars on the market.
1. Depreciation – The Hidden $20K Punch
Depreciation is the #1 cost nobody talks about.
McLaren
Depreciation is brutal. You can easily lose $15,000–$25,000 per year depending on miles and spec.
AMG GT-R
Much more stable. Expect around $5,000–$10,000 per year in depreciation.
911 Turbo
The king of value retention. Some years they even gain value.
Average: $3,000–$7,000 per year.
Winner: The 911 Turbo by a mile.
2. Maintenance & Repairs
This is where wallets get folded.
McLaren 570S / 600LT
Annual service: $2,000–$3,000
Unexpected repairs: $5,000–$15,000 (yes, really)
Common issues: suspension actuators, hydraulic systems, random electrical gremlins
Realistic yearly total: $7,000–$20,000
Mercedes-AMG GT-R
Annual service: $1,200–$2,000
Common repairs: brakes and rotors, heat-soak related issues if driven hard
Parts are expensive, but it’s still a Mercedes, not a full exotic
Realistic yearly total: $3,000–$6,000
Porsche 911 Turbo / Turbo S
Annual service: $1,000–$1,800
Repairs: rare, but Porsche parts are not cheap
PCCB carbon-ceramic brakes? You’re looking at $18,000 when they eventually need replacing
Realistic yearly total: $2,000–$4,000
3. Fuel Costs
Assuming about 6,000 miles per year and premium fuel at roughly $4/gallon:
McLaren: around $3,000 per year
AMG GT-R: around $2,200 per year
911 Turbo: around $2,000 per year
Doesn’t sound crazy by itself, but it stacks on top of everything else.
4. Insurance – The Silent Killer
This is the one that surprises most first-time supercar buyers.
McLaren
Insurance companies do not love these.
Expect $5,000–$9,000 per year depending on your age, record, and location.
AMG GT-R
More reasonable, but still expensive.
Around $3,000–$5,000 per year.
911 Turbo
Statistically, Porsche owners crash less and drive more responsibly.
Typical range: $2,500–$4,000 per year.
5. Tires
High-performance tires do not last long. Think 6,000–10,000 miles max if you actually drive the car.
McLaren: $1,800–$2,600 per set
AMG GT-R: $1,500–$2,200 per set
911 Turbo: $1,500–$2,400 per set
Track days or aggressive driving? Cut that lifespan in half.
6. Mods – The Real Money Pit
Let’s be honest: if you’re buying these cars, you’re probably not leaving them stock.
Typical mod prices:
Performance exhaust: $2,000–$8,000
Tune: $1,000–$3,000
Wheels: $3,500–$9,000
Full PPF (paint protection film): $3,000–$7,000
Ceramic coating: $1,200–$2,000
You can avoid mods… but almost nobody does.
The REAL Yearly Cost (All-In)
Let’s pull it all together: depreciation + maintenance + fuel + insurance + tires.
(Mods are extra.)
McLaren 570S / 600LT
Estimated yearly cost: $25,000–$40,000
The car might seem “cheap” used, but keeping it alive is where the bill hits.
Mercedes-AMG GT-R
Estimated yearly cost: $12,000–$20,000
Your “budget” supercar that still makes insane power, especially with basic mods.
Porsche 911 Turbo / Turbo S
Estimated yearly cost: $10,000–$18,000
Usually the cheapest to own, often the fastest in real life, and easily the best at holding value.
So… Which One Should You Actually Buy?
If you want the fastest car with the least headaches:
👉 Porsche 911 Turbo
If you want the best sound and presence for the money:
👉 Mercedes-AMG GT-R
If you want the wildest experience and can afford chaos:
👉 McLaren
None of them are “cheap” to own.
But if you go in with your eyes open, they can be some of the best automotive experiences of your life.

If you want me to help you write a version of this post just for one of these cars (McLaren-only, GT-R-only, or 911-only) so you can turn this into a mini-series on the blog, tell me which one you want to start with and I’ll draft it next.
