Along with five years for the rest of its range

Holden has announced it will be offering a seven-year, unlimited-kilometre warranty on the new Commodore and Equinox until March 31.

“We want more and more people to come and take a look at just how good these vehicles are and experience some of the great engineering work from our talented engineers – our new seven-year warranty on Commodore and Equinox shows just how confident we are," said Mark Harland, Holden executive director of marketing.

The rest of the brand's '2018 plate' models will come with a five-year warranty and five years of roadside assist as part of the same promotion, while the Colorado and Trailblazer will also get three years of free, scheduled servicing.

All 2017-plate models will get the same perks as the Colorado: three years free servicing, five-years of warranty and roadside assist.

This isn't the first time Holden has used a longer warranty to try and lure buyers into showrooms – the brand ran a seven-year, 175,000km warranty promotion in October, November and December of last year.

The program wrapped up as we waved goodbye to 2017, with Holden managing director, Mark Bernhard, crediting it for an uptick in sales, but arguing it was "just another" promotion.

“The industry runs programs all the time… sometimes they are [around] servicing, sometimes they’re warranty, sometimes they’re just lower prices,” Bernhard told CarAdvice in December last year.

“There’s a host of different programs, this is just another one, which we think resonates with customers, particularly at a point when we closed the plant," he added, hot on the heels of Holden's plant closure in Elizabeth.

“It’s a combination of incentive and brand building. Certainly it helps us stand out a little bit more, but at the end of the day it’s a retail exercise to help us sell more cars.”

The current promotion runs until March 31. Whether we'll see more 'sporadic' seven-year warranty programs, or indeed Holden will bite the bullet and extend its regular three-year, 100,000km coverage remains to be seen.
