MARKET ANALYSIS
Stag (1970 to 1978)

The Triumph Stag, a sophisticated 2+2 grand tourer manufactured between 1970 and 1978, was envisioned as a direct British rival to the Mercedes-Benz SL, featuring a unique T-bar integrated roll cage for safety and structural rigidity. In the 2026 Australian market, the Stag remains a highly desirable classic, particularly valued for its smooth 3.0-litre Triumph V8 engine and its status as a comfortable, long-distance cruiser well-suited for regional rallies like the upcoming TSOA National Rally in Toowoomba. This enduring popularity is supported by a huge Australian aftermarket world, with local owners often opting for essential upgrades like high-performance Davies Craig electric water pumps and uprated radiators to manage the V8's thermal needs in the local climate. While manual cars with overdrive are the rarest and most sought-after by enthusiasts, the majority of the market consists of three-speed automatics, which currently maintain a robust market value; as of March 2026, physically sound "drivers" typically start around $20,000, while pristine, well-documented examples are reaching between $35,000 and $45,000 at local auctions.
