Used 2025 Audi S5 for Sale nearLongmont, CO

Is the 2025 Audi S5 a good car?

Yes — 5/5 owners rate the 2025 Audi S5, and CarGurus experts give it 7.00/10. The model scores 9/10 across Form and function and Technology.

The 2025 Audi S5 is positioned as a redesigned sportback that blends performance, comfort, utility, and modern tech, with enough room for a family of four. That makes it a better fit if you want a car that can handle a favorite back road without giving up everyday usefulness.

Trade-offs: the styling is described as uninspired, the highway ride can be noisy, and the driver assistance tech is unimpressive. Even so, the S5’s strong cargo utility and impressive cabin technology help offset those drawbacks for buyers who value a sporty daily driver.

Good and great deals account for 36.6% of listings, so you still have some room to shop selectively.

Is the 2025 Audi S5 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The 2025 Audi S5 is presented as a refined, well-built sportback with strong everyday usability, and the expert evaluation emphasizes its solid performance and high-tech cabin. The turbocharged V6 is described as a deeply satisfying powerplant with seemingly limitless power, and the car’s overall execution suggests a premium ownership experience rather than a fragile one.

Audi also includes a generous trial subscription to connected services, which adds some early ownership value. For used buyers, the main long-term risk is less about basic dependability and more about living with a car that can be loud on the highway and expensive to keep satisfying if you expect it to behave like a quiet luxury sedan.

What should I look for when buying a used 2025 Audi S5?

Accident-free inventory is excellent at 97.9% — clean inventory, standard diligence applies.

You should still run a history report, confirm the car’s service records, and prioritize a thorough test drive because the S5’s appeal depends heavily on condition and equipment. Pay close attention to road noise, steering feel, and whether the driver-assistance systems behave the way you expect in real-world driving.

Key things to evaluate:

• Trim level: Premium, Premium Plus, and Prestige are the trims explicitly identified. The base Premium includes the core sportback utility and the standard driver-assistance suite, while the higher trims add more luxury and convenience equipment. If you want the most complete feature set, the Prestige is the one to focus on.
• Powertrain: The S5 uses a turbocharged 3.0-liter V6 with 362 horsepower and 406 pound-feet of torque, paired with a seven-speed dual-clutch automated manual transmission and standard Quattro all-wheel drive. It is tuned for strong acceleration and enthusiastic driving, but it also carries a heavier curb weight and returns 22 mpg in combined driving.
• Safety package: Every Premium includes forward collision warning, automatic emergency braking, lane departure warning, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, automatic high-beam headlights, traffic sign recognition, front and rear parking sensors, safe exit warning, and Emergency Assist. Premium Plus and Prestige add Adaptive Cruise Assist, which brings lane-centering assist, plus a surround-view camera system and Park Assist Plus.
• Infotainment: The cabin centers on an 11.9-inch digital instrument display and a 14.5-inch MMI touchscreen. Prestige adds a 10.9-inch passenger touchscreen. Wireless smartphone integration is not mentioned, but the Audi Digital Assistant is highlighted as responsive, and connected services are complimentary for three years.
• Fuel efficiency: The official combined rating is 22 mpg, and the test loop returned 21.8 mpg.

Which 2025 Audi S5 trim should I buy?

The 2025 Audi S5 is offered in 3 trim levels: Premium, Premium Plus, and Prestige.

Here's the short version:

• Premium: This is the trim to start with if you want the S5’s core appeal without stretching for extras. You still get the turbo V6, Quattro AWD, the sportback body style, and the full standard safety suite, so it covers the essentials well.
• Premium Plus: This is the best-value trim for many shoppers because it adds meaningful convenience and tech upgrades, including Adaptive Cruise Assist, a surround-view camera system, Park Assist Plus, a head-up display, and the upgraded Bang & Olufsen audio system.
• Prestige: Choose this if you want the most luxurious and tech-heavy version, including the passenger touchscreen and adaptive-damping sport suspension. It is the most complete expression of the S5, but the added equipment is more about polish than a dramatic change in character.

The safety package is strongest on Premium Plus and Prestige because those trims add Adaptive Cruise Assist and its lane-centering function.

Is now a good time to buy a used 2025 Audi S5?

This looks like a moderate, selective buyer’s market, so you can shop patiently but still move quickly on the right car.

• Deal availability: 36.6% of listings are priced as good or great deals.
• Inventory: There are 145 listings available.
• Clean inventory: 97.9% of listings are accident-free.

If you find a listing below $58,042.73, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2025 Audi S5 safe?

The 2025 Audi S5 earns a 4/10 safety score from our experts.

Every 2025 Audi S5 Premium includes forward collision warning, automatic emergency braking, lane departure warning, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, automatic high-beam headlights, traffic sign recognition, front and rear parking sensors, safe exit warning, and Emergency Assist. Premium Plus and Prestige add Adaptive Cruise Assist, which brings lane-centering assist, along with a surround-view camera system and Park Assist Plus.

The main caveat is that the lane-assist behavior is described as overly aggressive and sometimes inaccurate, and the system also produced an unexplainable braking event during testing. That makes the driver-assistance tech something you should evaluate carefully on your own test drive.

Should I buy a 2025 Audi S5 or consider a different year?

If you're weighing the 2025 against nearby model years, here's how to think about it:

Choose the 2025 if:

• 36.6% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 97.9% — clean inventory, standard diligence applies.
• Owners rate it 5/5 — a strong satisfaction signal.
• The redesigned S5 is a multi-talented sportback with performance, comfort, utility, and the latest technology, and the new Audi Digital Stage technology impresses.

The bottom line: If you want the redesigned S5’s blend of driving excitement, cargo utility, and high-tech cabin design, the 2025 is the one to target. If your priority is simply getting into an Audi sportback at a lower price, a different year may be worth considering, but the 2025 is the stronger choice if you want the newest version of the formula.
