Audi RS6 (C6)

The Audi RS6 C6 has appreciated 14.2% year-over-year to a current median of AUD $30,708, signalling steady if modest gains in the Australian market. With only two transactions tracked over the past 12 months, the price foundation remains thin, though the consistent upward direction suggests underlying support for the model.

These sales have centred on extremely low-mileage examples, averaging just 902 kilometres, indicating that collectors pursuing this generation favour nearly-new or lightly-driven specimens. This condition emphasis may reflect the model's transition into collectible territory as it ages out of regular ownership.

The RS6 C6 occupies the stable modern classic tier—a relatively young segment where production volumes and original retail pricing data are not yet standardized in the secondary market. Desirability remains low relative to its collectibility score, a pattern typical of performance models that have yet to establish strong narrative appeal among traditional collectors.

Liquidity remains illiquid, with zero active listings at present and only two sales in the tracked sample. This thinness creates meaningful friction for both buyers and sellers, though it also insulates prices from rapid downward pressure typical of more widely available performance cars.

Projections indicate base appreciation to AUD $41,922 over three years (36.5% growth) and AUD $46,436 over five years (51.2% growth). These forecasts rest on the assumption that the model's appeal as a modern classic solidifies and supply remains constrained, a reasonable but not certain outcome given current low desirability signals.
