Is the 2019 Audi S4 a good car?

Yes — the 2019 Audi S4 earns a 5/5 user rating, which lines up with its appeal as a fast, upscale sedan that still feels comfortable in daily driving. It combines strong straight-line performance, standard all-wheel drive, and a well-equipped cabin with useful tech, so you get a car that works well as both a spirited commuter and a refined all-around luxury sedan. It is not the sharpest handler in its class, but it still delivers plenty of thrust and a polished driving experience. With 37.1% of listings marked as good or great deals, you have a meaningful number of value-oriented options to consider.

Is the 2019 Audi S4 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction. The 2019 Audi S4 is described as a solid choice for buyers who want performance and refinement, but it also comes with the reminder that Audi reliability is rated below average by RepairPal. That means you should expect a premium-car ownership experience where maintenance history and upkeep matter. For used buyers, the long-term risk is less about the car’s core appeal and more about whether the previous owner kept up with service and avoided deferred maintenance.

What should I look for when buying a used 2019 Audi S4?

At 71.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was cosmetic or structural. Then prioritize a pre-purchase inspection, with extra attention to signs of uneven panel gaps, paint mismatch, tire wear, and any evidence of incomplete repairs. Because this is a performance-oriented luxury sedan, you should also focus on overall condition and maintenance records, since a well-kept example is likely to be a much better ownership experience than one with a vague service history.
