Six-time Bathurst 1000 winner Garth Tander sits among exalted company in the history of Australian motorsport, as a dominant figure in the modern era of the annual 'Great Race' at Mount Panorama.

A lanky kid from Perth obsessed by going fast, Garth achieved skill and speed in a race car that took him to places very few racers ever reach, including the crowning achievement of V8 Supercars Championship in 2007.

He's raced wheel-to-wheel against a rotating cast of legends, from the era of Dick Johnson and Larry Perkins to Mark Skaife, Craig Lowndes, Marcos Ambrose and modern heroes including Shane van Gisbergen, Scott McLaughlin and Chaz Mostert.

Along the way Garth has experienced the towering heights and bitter lows of life as a professional athlete in the brutal world of motorsport, where being fast behind the wheel is only part of the job, and the ongoing drive to lead, improve and succeed never stops.

Now, as he moves into the next phase of his professional motorsport life as a television broadcaster and mentor, Tander opens up on the trials and tribulations of his career, the off-track pillars of his on-track success, and the shock team exits, and provides insights into the ever-present backroom politics of a multimillion-dollar sport.

The Finish Line is Garth's racing and life story, from a key figure of the sport, set in the golden era of V8 Supercar racing and amid the amazing Holden and Ford rivalry that raged through the 1990s, 2000s and 2010s.
