You’ve seen the depreciated supercar videos. Someone buys a six-figure German monster for the price of a loaded Camry and then spends the next six months crying over a hydraulic leak. But honestly, the 2019 Mercedes Benz AMG lineup—specifically the GT—is a different beast entirely. It feels like the last year Mercedes really cared about tactile aggression before everything became a giant iPad on wheels.
The 2019 model year was a pivotal moment for the AMG brand. It wasn’t just about putting a bigger turbo on a standard engine. No, this was the year of the mid-cycle refresh for the GT, and it brought some serious hardware to the table. If you're looking for that perfect intersection of "modern enough to not be a headache" and "old-school enough to scare you a little," this is it.
The V8 Biturbo Heartbeat
Let’s talk about that engine. The M178 4.0-liter V8 biturbo. It’s a "hot inside V" configuration. Basically, the turbos are tucked inside the cylinder banks rather than hanging off the sides. Why does this matter? It makes the whole package tiny. It also cuts down on turbo lag because the air doesn't have to travel three miles to get where it's going.
In the 2019 Mercedes Benz AMG GT, you’re looking at output levels that range from 469 horsepower in the base model all the way up to 577 in the GT R. But here’s the thing: those numbers are conservative. Mercedes-AMG has a long history of under-promising and over-delivering on torque. When you pin the throttle, it doesn't just accelerate. It lunges. It’s violent.
I’ve talked to several shop owners who specialize in German performance, like those over at Renntech, and they’ll tell you the 2019 internals are incredibly over-engineered. They can handle way more power than the factory gives them. It’s a tuner’s dream, frankly.
What changed in 2019?
If you're cross-shopping a 2018 and a 2019, look at the steering wheel. That’s the easiest tell. The 2019 Mercedes Benz AMG GT got the new steering wheel with the integrated drive mode dials. It’s a small detail, but it makes a massive difference in how you interact with the car. You don't have to fumble with the center console while you're trying to take a corner; you just thumb a dial to go from Comfort to Sport+.
The 2019 also introduced the AMG Dynamics system. Think of it like a digital brain that predicts what you're doing before you do it. It works with the ESP (Electronic Stability Program) to calculate how much slip you can handle based on your steering angle and speed. It’s not intrusive. It doesn't feel like a computer is driving for you. It feels like you’re suddenly a better driver than you actually are.

The GT C vs. The GT R
Most people want the GT R because of the "Beast of the Green Hell" marketing. It’s green. It has a giant wing. It’s cool. But if you’re actually going to drive this on the street? Get the GT C.
The GT C is the sleeper hit of the 2019 Mercedes Benz AMG range. It shares the wider rear fenders of the GT R, meaning you get that aggressive, wide-hipped stance. It also has the rear-axle steering. At low speeds, the rear wheels turn opposite to the fronts, making the car feel shorter than it is. It helps with parking. At high speeds, they turn with the fronts for stability. It’s magic.
- GT Base: 469 hp / 465 lb-ft
- GT S: 515 hp / 494 lb-ft
- GT C: 550 hp / 502 lb-ft
- GT R: 577 hp / 516 lb-ft
The GT R is stiff. Like, "visit your chiropractor once a week" stiff. Unless you live next to a track, the GT C’s adaptive dampers are much more forgiving for weekend trips.
The 4-Door Coupe: A different animal
We can't talk about the 2019 Mercedes Benz AMG without mentioning the GT 4-Door Coupe. This was the debut year. People were confused. Was it a CLS? Was it an E-Class? Mercedes said it was a four-door version of the GT sports car.
In reality, it's a bit of a Frankenstein. It’s based on a highly modified version of the MRA platform. It’s heavy. Really heavy. But the AMG GT 63 S version of this car is a physics-defying monster. It held the Nürburgring record for a luxury four-seater for a reason.
The interior of the 4-door is miles ahead of the 2-door in terms of tech. You get the dual 12.3-inch screens. It’s plush. You can take three friends to lunch and then melt their brains with a 3.1-second 0-60 mph launch on the way back. It’s ridiculous and unnecessary, which is exactly why it’s great.

What usually goes wrong?
Nothing is perfect. Especially not a high-performance German car. If you’re hunting for a used 2019 Mercedes Benz AMG, keep an eye on a few things.
First, the brakes. If the car has Carbon Ceramics, they’ll last forever under normal use, but if they do need replacing, you’re looking at a bill that could buy a used Honda. Check for "pitting" or chips on the rotor edges. Second, the driveshafts on the early 2019 GT 4-doors had some vibration issues. Mercedes issued a few service bulletins about it.
Also, the active aero. The front "Airpanel" (those vertical slats in the grille) can sometimes get stuck. If they don't open, the car will overheat. It’s a simple mechanical failure, but it’s expensive to fix because you usually have to take the whole bumper off.
Real-world ownership costs
Expect to pay for tires. Often. These cars are rear-biased and have massive amounts of torque. If you have a heavy right foot, you’ll be buying a new set of Michelin Pilot Sport 4S tires every 8,000 to 10,000 miles.
Service A and Service B are the standard Mercedes maintenance intervals. Service A is basically an oil change and inspection, usually around $400-$600. Service B is more involved (filters, brake fluid, etc.) and can run you $1,200-$1,800 depending on the dealership. Don't skip these. The M178 engine is reliable, but it doesn't tolerate neglect.
The 2019 Mercedes Benz AMG as an investment
Is it going to go up in value? Probably not yet. But it’s holding steady. While the newer 2024 models are going to a 2+2 seating configuration and AWD, the 2019 GT remains a pure, rear-wheel-drive-biased muscle car in a tuxedo.

Collectors are starting to look at the 2019-2020 models as the "peak" of the first-gen GT. They have the upgraded interior tech but still retain the raw hydraulic-feeling steering and the aggressive transmission mapping that the newer, more "refined" models have smoothed out.
How to buy one without getting burned
If you're serious about getting into a 2019 Mercedes Benz AMG, don't just look at the odometer. Look at the "Launch Control" counter if you can get a PPI (Pre-Purchase Inspection) from a dealer. It tells you exactly how many times the previous owner tried to play drag racer.
- Get a Paint Meter: AMG GTs have aluminum bodies. Repairs are hard. If a panel has thick bondo, walk away.
- Check the "V" for oil: Small leaks in the turbo oil lines are common and can be a fire hazard if left alone.
- Service History is King: If there isn't a digital or physical trail of every oil change, the car isn't worth the risk.
- Listen to the transmission: The 7-speed dual-clutch should be snappy. If it feels "slushy" or hesitant when cold, it might need a fluid flush or a software recalibration.
Why this year matters
Ultimately, the 2019 Mercedes Benz AMG represents a specific era of Mercedes. It’s the era before the "EQ" electric push took over. It’s loud. It pops and bangs on the downshifts. It has a presence that a Tesla or a newer, muffled hybrid AMG just can’t replicate.
When you sit in the cockpit, you’re surrounded by a massive center console that makes you feel like you’re in a fighter jet. The visibility is terrible. The hood is ten feet long. It’s impractical in all the ways a sports car should be.
If you find a well-maintained GT C in a color like Selenite Grey Magno, buy it. You'll get the wide body, the rear steering, and the refreshed interior without the "track-only" compromises of the GT R. It's the best version of one of the best cars AMG ever built.
To move forward with a purchase, your first step should be to secure a VIN-specific build sheet. This will tell you if the car was equipped with the optional AMG Ride Control or the high-end Burmester 3D surround sound, both of which significantly impact resale value and daily drivability. Once you have the build sheet, schedule a specialized PPI that specifically includes an inspection of the active engine mounts, as these are a known high-wear item on the 2019 models that can cost thousands to replace if they've begun to leak or fail.
