It was a personal decision..."" (Amon, on his retirement in 1976)However, Walter Wolf contacted Amon and persuaded him to drive for his Wolf–Williams team in the North American races near the end of the season. After recording some promising times in preparation for the Canadian GP, however, Amon was involved in a heavy collision with another car during qualifying and once again was lucky to walk away unharmed. He then did not take part in either the Canadian or United States Grands Prix. Amon turned down an offer of a full-time F1 drive for 1977, but did attempt a return to Can-Am racing in 1977 with a Wolf-Dallara WD1. However, after only one race he quit, saying "I'm just not enjoying this anymore". His place was taken by the young and then unknown Canadian Gilles Villeneuve, whom Amon would, later that year, recommend to Enzo Ferrari. In the meantime, Amon returned once again to New Zealand, this time to retire from F1 motor racing for good. Amon came out of retirement for a one-off appearance in the 2003 Dunlop Targa New Zealand with motorsport commentator Murray Walker as his navigator. The pair completed the week-long Auckland to Wellington Tarmac Rally in a Toyota Camry Sportivo, the same car previously used by Walker and Colin Bond in Australia's Targa Tasmania. After his retirement from F1, Amon dedicated himself to running the family farm in New Zealand's Manawatu District for many years. After retiring from farming, he lived in Taupo in New Zealand's North Island. In the early 1980s he became more well known in New Zealand from test-driving vehicles on the TV motoring series "Motor Show" and later consulted for Toyota New Zealand, tuning the 1984 Toyota Corolla and subsequent cars for sale there. He also appeared in TV commercials for the company, where much was made of the acclaim he won from Enzo Ferrari. Amon participated in the 2004 EnergyWise Rally where he won ahead of Brian Cowan. Amon drove a Toyota Prius for the event. Amon was involved in the design of the upgraded Taupo Motorsport Park circuit, used for the New Zealand round of the 2006-07 A1 Grand Prix season in January 2007. At the New Zealand Festival of Motor Racing in 2011, Amon's life and career were honoured with a selection of his cars being driven and also used the event to raise funds for the Bruce McLaren trust. Amon was also honoured at the festival in January 2013.
