This, dear readers, is what commitment looks like. In 1976 Canadian businessman Bill MacEachern took delivery of a brand-new Porsche 911 Turbo. Rather than lock it away in the hope it might gain value, or use it only sparingly at weekends, MacEachern decided to drive it. Lots. 44 years of almost daily use has seen it rack up an astonishing 779,000 miles. And it’s still going strong.

MacEachern’s is a ‘G-model’, 930-era 911 – the 350th built. Specced in blue with a tan interior, it’s been driven thousands of miles all over the United States – from Florida to California and beyond.

Of course it’s gone wrong on occasion. MacEachern was en route to Monterey in California once when a fan pulley broke, but he found a shop to bodge it, while in 2009 it was involved in a small collision, when an SUV turned right across its path. But it’s always come back fighting, always survived.

It crossed the million-kilometre mark in 2012, prompting a champagne-fuelled celebration, and today its odometer reads 1,253,584 kilometres, around 779,000 miles. More than that, probably, since we got wind of this.

Anyone you know have a high-miler they just can’t part with?
