In 2025, Waimak Classic Cars achieved a significant milestone in its collector vehicle journey with the successful tracking and acquisition of one of the most storied Jaguar XK120s in New Zealand, widely known among enthusiasts as the “Middlemass XK120.”
Originally owned and raced by Christchurch racer Dave Silcock, the car, a beautifully proportioned and highly regarded historic example of the iconic open two-seater, had long been recognised within New Zealand classic car circles for its provenance, racing history, and connection to notable early custodianship. Its reputation had grown over decades, becoming something of a reference point among Jaguar enthusiasts and collectors familiar with the country’s most significant XK models.
The search for the vehicle was a deliberate and patient process, involving extensive research, networking within the classic car community, and careful tracing of ownership history. When the opportunity finally arose, Waimak Classic Cars acted decisively to secure the car, recognising its importance not only as a collectible Jaguar, but as a preserved piece of New Zealand motoring heritage.
Built by Jaguar Cars, the XK120 is regarded as one of the most important sports cars of the post-war era. Upon its release in 1948, it was the fastest production car in the world, celebrated for its flowing aluminium bodywork, advanced engineering, and remarkable performance for its time. Today, surviving examples, particularly those with known history and notable provenance, are highly sought after on the international collector market.
The Middlemass XK120 stands out not only for its inherent design and engineering pedigree, but also for its well-documented racing life in New Zealand, where it became part of the country’s early enthusiast and historic motoring culture. Its identity is closely tied to the stories, ownership, and preservation efforts that have kept it known within specialist circles for many years.
For Waimak Classic Cars, the acquisition represents more than just the addition of another significant vehicle to the collection, it is the securing of an important historical artefact. Cars of this calibre continue to attract strong international interest, with values for well-documented XK120s remaining robust and showing long-term appreciation trends, particularly for examples with strong provenance and originality.
The Middlemass XK120 now forms part of a curated collection focused on historically significant, emotionally engaging, and investment-grade collector vehicles. It will be preserved, maintained, and shared in a way that honours its history while allowing enthusiasts to continue appreciating its beauty and importance.
