A few comments on your options:
(*) Holden announced that the Redline HF20's were $1500 when the VF2 was announced (FYI)
(*) they come with stainless sill-plate inserts already, the extra-cost ones are just inserts with different logos; but unlike stainless sill-plates of old they're just wee little things for appearance only, they offer no protection
(*) I
love our folding luggage organiser; the shopping tote-bags fold neatly into the pocket with the elasticised webbing, shopping & individual things go into the organiser, and the load-space is always neat & organised & nothing slides around
(*) what SnowDoggyDog says about prices is very true, check eBay for example (although our local dealer was cheaper for the sheepskin seat-covers) ... but consider fitting, stuff like grille inserts are a bit involved when fitting & if the dealer price includes fitting there're a few hours you'll save (not to mention me being antsy about pulling the bumper off my brand new car!)
(*) negotiating, when options are involved, is wierd. You know how it works, each side invents a reason for their assertion on whether the price could come down or stay where it is ... but the initial price you're given with all the options has full-priced options with that being a large chunk of the dealer profit. Then you start negotiating down, reducing the overall price; and then because Holden has published option prices online (and you've also researched prices on eBay), and the dealer has totally different prices on all options, you remove the ones which are way more than the Holden price & the cost comes down by those full profit-heavy prices. It was a bit strange, I'd have thought they should only reduce the price by
their cost rather than the full RRP. Anyhoo, the point being that I reckon that the negotiation is easier for a non-haggler if you start by specifying
every option, negotiate the fully-loaded vehicle down, and
then start removing all options that aren't cheaper than you expect.
