The 2003 Audi RS6 (C5 generation) is a high-performance luxury sedan and Avant (wagon) based on the A6. Produced from 2002-2004 (2003 model year in the US), it was only available as a single, well-equipped trim. Its defining characteristic is the twin-turbocharged 4.2-liter V8 engine. New, it retailed for around $75,000. Its potent performance and understated styling, combined with Audi's Quattro all-wheel drive, made it a popular "sleeper" car.
The Good
The 2003 Audi RS6 offers thrilling performance from its twin-turbo V8, coupled with the practicality of a sedan or wagon. The Quattro system provides excellent grip and stability. The luxurious interior delivers comfort, while the understated design appeals to those who appreciate a "sleeper" car. Although not the most efficient, it offers a unique blend of power and sophistication.
The Bad

The suspension, particularly the DRC (Dynamic Ride Control), is a common failure point and expensive to repair. High maintenance costs and potential for electrical issues are also areas to watch out for.

What Problems Does the 2003 Audi RS6 Have?
The 2003 Audi RS6 is plagued by several well-documented reliability concerns. One major issue is the engine's susceptibility to carbon buildup on the intake valves, requiring costly cleaning or repair. Oil leaks are also common, stemming from various seals and gaskets throughout the engine. The Dynamic Ride Control (DRC) suspension system is notorious for failing, leading to poor handling and expensive replacement costs. The original DRC is often replaced with aftermarket coilover systems.
Transmission issues, though less frequent, have been reported. Electrical problems, including faulty sensors and wiring harnesses, are also not uncommon. Recalls for the 2003 RS6 are relatively limited compared to some other vehicles of the era, but it's crucial to check for any outstanding safety recalls. Long-term reliability is a significant concern, as many of these issues become more prevalent and costly as the car ages. Maintaining an RS6 requires meticulous care and a willingness to address potential problems proactively to prevent further damage.

How long will the 2003 Audi RS6 last?
Given their age, most 2003 Audi RS6 models have accumulated significant mileage. Expect to find examples ranging from 100,000 to over 200,000 miles. The longevity of an RS6 heavily depends on maintenance habits. Cars with meticulous service records, using quality parts and fluids, are likely to last longer.
The engine, while powerful, can suffer from wear and tear over time, leading to increased oil consumption and reduced performance. The automatic transmission can also show signs of age, potentially requiring rebuilding or replacement. Rust can become a concern, especially in regions with harsh winters. Regularly addressing maintenance needs is crucial for extending the lifespan of an RS6.

2003 Audi RS6 Prices and Market Value
When new, the 2003 Audi RS6 retailed for approximately $75,000. Today, used market prices vary significantly based on condition, mileage, and service history. Expect to find examples ranging from $15,000 to $30,000, or even higher for exceptionally well-maintained vehicles with low mileage. The RS6 has depreciated considerably due to its age, maintenance costs, and the availability of newer, more technologically advanced performance cars. Factors affecting resale value include a comprehensive service history, the absence of major mechanical issues, and overall cosmetic condition. The Avant (wagon) version sometimes commands a slight premium due to its added practicality and rarity.
2003 Audi RS6 Cost of Ownership
Owning a 2003 Audi RS6 is not for the faint of heart when it comes to costs. Insurance can be higher than average due to the car's performance capabilities. Fuel economy is poor, and premium fuel is required. Maintenance and repair costs are substantial, as parts can be expensive and specialized labor is often necessary. Long-term ownership can be costly due to the potential for major repairs, particularly related to the engine, transmission, and suspension. It is definitely a costly vehicle to own and maintain.

How Does the 2003 Audi RS6 Compare to Other Sedan?
The 2003 Audi RS6 competed with other performance sedans and wagons like the BMW M5 (E39) and the Mercedes-Benz E55 AMG (W211). In terms of performance, the RS6 was comparable, offering similar horsepower and acceleration. Feature-wise, the RS6 held its own, offering a luxurious interior and a decent array of tech for its time. However, reliability is where the RS6 falls short compared to its rivals. The BMW M5, while also requiring maintenance, is generally considered more reliable. The Mercedes E55 AMG is also known for its robust engine.
Price-wise, used RS6 models can be slightly more affordable than comparable M5s, but repair costs can quickly offset any initial savings. As alternatives, consider a well-maintained BMW M5 (E39) for a more engaging driving experience and potentially better reliability, or a Mercedes-Benz E55 AMG (W211) for brute force power and reasonable reliability. If you value all-weather capability and a more understated style, and are prepared for the associated maintenance costs, the RS6 is unique. However, from a purely practical standpoint, the M5 or E55 AMG might be better choices.

Final Verdict: Is the 2003 Audi RS6 a Good Sedan?
The 2003 Audi RS6 is a compelling choice for the enthusiast who appreciates a blend of performance, luxury, and understated style. It's ideal for someone who is prepared to handle the high maintenance costs and potential for expensive repairs. Whether it's worth buying depends on your budget and willingness to invest in upkeep.

If you're seeking a reliable daily driver with low running costs, the RS6 is not for you. However, if you desire a unique and powerful piece of automotive history and are willing to accept the associated risks, the 2003 Audi RS6 can be a rewarding ownership experience.
