Commodore
Overview
The last of the locally-built, rear-drive Commodores - sold as Evoke, SV6, SS, SS-V, Calais and Calais V across sedan, Sportwagon and ute body styles, with the long-wheelbase Caprice/WM as a sibling. The VF was a heavily reworked VE: lighter aluminium panels, a far better interior, electric power steering and the slick MyLink system. Engine choice defines the buy. The mainstream 3.6L LFX SIDI V6 is the volume seller and generally durable, but direct injection brings intake carbon and the Alloytec-family timing chain can still stretch at high km. A port-injected 3.6L LPG V6 was offered to 2015. V8 buyers got the 6.0L L77 (with Active Fuel Management cylinder deactivation) until the September 2015 VF Series II swapped in the 6.2L LS3 - the most desirable and now strongly-appreciating engine. As collectible Aussie muscle the SS/SS-V V8s are climbing in value, while V6 sedans remain some of the best big-car value in the country. Watch for ex-fleet/taxi (LPG) high-km cars and hard-driven V8s.
Engines & variants
