Order date = whenever you signed a contract for the car and paid a deposit on it. Up until October last year that date was firm and Holden audits deals to make sure that dealers aren't being dodgy (I.e they check customers contracts and want written evidence of deposits paid etc) to make sure that people weren't getting given extra warranty etc, when they weren't entitled to it. They made the change so that if you signed up one month and then Holden changed the offer the following month and you thought the new offer was better, then you could change. For example, let say you signed up last month and they were doing free servicing and then this month they changed to 7 years warranty, if you complained/asked the dealer to change, there's a form we can fill out and get signed that allows this change to occur. At the same time, if you legitimately signed up for your car in July, knowing you were getting no 'freebies' and now all of a sudden they're giving them away this month, the dealer doesn't have to give you this months offer, because the terms and conditions of the offer state for orders taken between 1/10/2017 and 31/12/2017. The warranty contribution cost to the dealer is $750. If they offer it to you for this, then you've done well, because really we're not supposed to change the customer order date beyond 30 days and they do audit this and a dealer can then be charged back the full cost of the warrranty or whatever promotion that is running. We couldn't even buy a 4 year extension of new car warranty from Allianz for that amount and it would usually probably retail for upwards of $2,000.
