HOW do you replace a Classic? If it’s the Holden TS Astra Classic, then the answer is by benchmarking it, which is what Holden says it has tried to do with the new JF Viva, a Daewoo Lacetti-derived small hatchback, wagon or sedan that it hopes will win the hearts and wallets of middle Australia like its Opel-based predecessor. And on paper, Holden may have succeeded, especially when you factor the high-specification levels into that sharp $17,990 opening price. But what of the TS Astra’s quality and charm? And do they matter anyway? Only time and sales figures will tell.
