Summary
With 242 currently listed for sale and an average price of $36,024, 32.6% of 2023 Genesis G80s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2023 Genesis G80 5 / 5 stars.
89.7% of 2023 Genesis G80 models on CarGurus are accident free.
Why it stands out
The 2023 Genesis G80 stands out as a luxury sedan that pairs strong value with a polished, modern feel. By this generation, Genesis had given the G80 a stiffer, lighter chassis with a lower center of gravity, and the car also adopted the brand’s “Athletic Elegance” design language with a large “Crest Grille” and double-lined “Quad Lamp” lighting elements. Inside, Genesis used its “Beauty of White Space” approach to emphasize outward visibility, and the cabin featured a 12.3-inch digital instrument cluster, a wide 14.5-inch infotainment screen, and a head-up display. It was also priced well below comparable German luxury sedans when new, which helped make it an especially appealing choice for buyers who wanted upscale features without the usual premium-brand cost.
For 2023, the G80’s powertrain lineup included a 2.5-liter inline-four with 300 horsepower and 311 pound-feet of torque, plus an optional 3.5-liter twin-turbo V6 with 375 hp and 391 lb-ft of torque. An eight-speed automatic was the only transmission, and both rear-wheel drive and all-wheel drive were available with either engine. Standard equipment was generous, too, with Highway Driving Assist II, Smart Cruise Control with Machine Learning, blind-spot monitors, and forward-collision warning all included. The G80 also earned strong safety recognition, including a Top Safety Pick+ award from the IIHS and a five-star overall safety rating from the NHTSA.
There are a few tradeoffs to keep in mind. The source describes the technology as unintuitive, the performance as fairly pedestrian, and the fuel economy as poor. Even so, the 2023 Genesis G80 remains distinctive because it combines a genuinely upscale interior, a broad set of standard safety features, and a price that undercuts many rivals while still feeling like a serious luxury sedan.

Is the 2023 Genesis G80 a good car?
Yes — the 2023 Genesis G80 earns a 5/5 user rating, which points to strong owner satisfaction. The overview describes it as a luxury sedan with a polished, modern feel, a genuinely upscale interior, and a value proposition that undercuts many comparable German luxury sedans. It also emphasizes generous standard equipment and a broad safety feature set, which makes it appealing if you want a premium-feeling sedan without paying top-tier luxury pricing. With 32.8% of listings marked as good or great deals, the market still offers some attractive opportunities.
Is the 2023 Genesis G80 reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The overview points to a stiff, lighter chassis, a lower center of gravity, and a generous standard safety package, all of which support confidence in everyday use. It also highlights strong safety recognition, including a Top Safety Pick+ award from the IIHS and a five-star overall safety rating from the NHTSA. For used buyers, the main long-term ownership risk is less about basic competence and more about making sure the car’s technology and condition have been well maintained.
What should I look for when buying a used 2023 Genesis G80?
Accident-free inventory is solid at 89.9% — always verify the vehicle history report.
You should still run a history report on any candidate, even if the listing looks clean at first glance. Prioritize a thorough inspection of the cabin technology, since the overview notes that the tech can be unintuitive, and make sure every major feature works as expected. Focus on overall condition, service history, and signs of wear that could affect the luxury-car experience you’re paying for.
Is now a good time to buy a used 2023 Genesis G80?
This looks like a moderate, selective buyer’s market, so you can be choosy if you’re patient.
- Deal availability: 32.8% of listings are priced as good or great deals.
- Inventory: There are 238 listings available.
- Price trend: Prices have softened 2.61% compared with last year.
- Clean inventory: 89.9% of listings are accident-free.
If you find a listing below $31,720, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2023 Genesis G80's resale value?
The current average of $36,001 sits slightly below last year's $36,968.
That decline suggests the market has eased a bit, which can help you buy at a more favorable entry point today. For a future seller, the softer trend means resale value may depend more on condition, mileage, and how well the car has been maintained. A well-kept example should still benefit from the model’s upscale image and strong feature content.
Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2023 Genesis G80 or consider a different year?
If you're weighing the 2023 against nearby model years, here's how to think about it:
Choose the 2023 if:
- 32.8% of listings are priced as good or great deals.
- Accident-free inventory is solid at 89.9% — always verify the vehicle history report.
- Price trend: Prices have softened 2.61% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
Consider the 2022 if:
- It emphasizes a quiet cabin and great ride quality.
The bottom line: If you want the stronger value play, the 2023 is the better primary target because it combines a lower average price, solid deal availability, and strong owner satisfaction. If you’re especially price-sensitive, the 2022 is worth a look for its comfort-focused appeal, but the 2023 gives you a compelling balance of value and market support.
