Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Thanks for all the responses All I can say is glad I asked the question. Few things learnt from this thread, such as QA testing at factory for random cars. Looks like it will be pot luck getting the lowest possible km's. I always thought new cars in stock with a few km's eg. 10 km plus were those that are test driven by potential customers, hence was kind of expecting a car from the factory to have minimal kms as no customer would have test driven it. I will ask the dealership to contact me when the car arrives. I will then go there and note the km, and then see how many extra kms the dealership puts on it before I take delivery (cross fingers, and hope less than 10k total on odometer - like some lucky people in this thread).
In the end, it really doesn't matter. Especially when it will likely have a lifespan of 20+ years and 400,000km+. In any event, you'd be extremely unlikely to hang onto it for that long.
Having 20km on it won't make it any 'less new' lol
