📖Generation guide
RS6 (C5) • 2002-2004
The RS6 (C5) was the last model before the C6 generation, featuring a Cosworth-tuned 4.2L twin-turbo V8. Only the sedan was officially imported to the US, making it a rare collector's item.
RS6 Avant (C5) • 2002-2004
The Avant variant was never officially imported to the US, making grey-market examples highly sought after as they become eligible under the 25-year import rule.

The B5 RS4 features a 2.7L twin-turbo V6 and was available only as an Avant globally, making it a desirable grey-market model in the US.
Known issues by generation
The Audi RS6 (C5) has specific known issues that collectors should be aware of. The 4.2L twin-turbo V8 features a rear-engine architecture that requires significant attention to the timing chain, tensioners, and guides, which must be replaced as a preventive measure at 80-120k miles—engine-out service that can cost between $5,000 to $15,000 at a dealer. Turbocharger K04 units may also experience wear, necessitating rebuilds in the $2,500 to $4,500 range. Additionally, the DRC suspension system can require a complete replacement due to pre-failure issues, costing up to $8,000.
Donation value by condition + generation
The value trajectory for the RS6 (C5) remains strong among collectors, particularly those with clean, low-mileage pedigrees. Values generally range from $30,000 to $60,000 for well-maintained US-market sedans, while grey-market Avants command a premium, often exceeding $60,000 if they meet EPA and DOT compliance. Preventive maintenance history is critical; vehicles lacking documentation for timing chain service or turbo rebuilds face significant collector devaluation. Original paint colors and unmodified condition enhance desirability, solidifying the RS6's status as a sought-after classic.
Donation process for this model
Donating your Audi RS6 (C5) is a straightforward process designed to ensure that your vehicle is properly valued within the collector market.
