From RS 4 and TT to RS 6 Avant GT: What Q4 Auction Sales Say About Audi’s Collector Market

In Episode 13 of All-Wheel Driven, we welcome back Audi Club contributor and auction analyst Steve Johnson, the trusted voice behind our Auction Watch blog series and quarterly quattro Magazine auction recaps.

Steve joins host Joe Kucinski to break down Q4 2025’s most compelling Audi auction trends, from long-roof legends like the RS 4 Avant to surprising supercar soft spots—and the growing collector momentum behind Audi’s upcoming F1 entry.

We look at why RS 6 Avant GTs are commanding $215K–$239K, whether the R8 GT Spyder has hit its price ceiling, and why Ur quattro values may be correcting. Plus, Steve explains how Audi’s motorsport branding—from IMSA to Formula 1—is already influencing buying behavior.

Other key takeaways:

RS 6 Avant Performance GT sales: instant classics or market peak?
B8 RS 5 depreciation may have bottomed out—smart buy or still risky?
Price swings between three RS 4 Avant builds—what drove the difference?
The R8 GT Spyder that didn’t sell—has the V10 market plateaued?
A 261-mph Bonneville S4 fails to attract serious bids—why?

We also dive into whether Audi’s upcoming F1 era could reshape the collector landscape, much like Ferrari or McLaren’s track-to-showroom strategy has done. Could cars like the RS e-tron GT or RS 6 GT become tomorrow’s F1-era halo collectibles?

Whether you’re a seasoned Audi collector or a curious shopper watching the auction space, Steve’s insights offer real-time value for buyers, sellers, and brand enthusiasts alike.
