What exactly are you wanting to know? If it's 06 it is a very early VE so yes first model I'd expect.
You're lucky you must have got a good engine, or it's had more oil changes than the service schedule suggested.
My uncle's 06 Omega went bang in about 2015. My 07 is still strong.
Thank you again I am just curious about just how early it might be, but unless its some engineering sample or ex cop car(highly unlikely) I know its still largely worthless unless its reliable.
I was hoping there was some kind of register in the wild. There is a former holden dealer here so I will ask them.
In my case its never had the chains done though has had the startup rattle(phasers?) for 150000ks now in my ownership. Got it over 5 years ago with 95K on the clock and did the right things mostly since - oil changes. Water inlet gaskets and non platinum plugs in it were the worst things we found - they'd obviously never figured out the gasket and it took me a while to find someone that did . Transmission needs a rebuild or replace too at this point - just holding first too long then jolting into 2nd sometimes so not done for yet.
Motor is throwing misfire codes 2/4/6 so I'm about to investigate that properly but I know it has a partially seized throttle body unit. It will run smooth after a reset but quickly throws codes so the engine is not kaput. Just wondering if its worth keeping but I've got parts and now a damaged 2007 also a Leo with good motor and trans so its mostly how much work i want to do and/or pay for I think - i'm no mechanic and I'm not near any of the cheaper and better commodore specialists I see on here. We'll get the manifold off and clean up or replace what needs it.
Transmission and misfire codes started after i got a swapover std exhaust last year at a local so called holden wrecker/expert. I think they 'italian tuned' it too hard after an oxy sensor/engine clean kit honestly.
