I recently bought a 2014 manual VF SS storm (sedan) for 39,500 with 10 years warranty.
(5 years dealer all components and then 5y holden with only engine + gearbox and some other stuff etc)
Lowered, no tinting, bar what comes on the glass standard and...cant remember the name of the colour....its black metallic basically. 200km on the clock. (it was a showroom car basically that the owner of the dealership drove home occasionaly)
Had to wait a few weeks before picking it up because of holden giving the dealer money for depreciation or some crap liek that....basically it would of been 42k if I didnt want to wait the 2 weeks.....and then for not much more I could have probably got an SSV.....
A golf buddy of my dads got a ssv redline for 38k but thats because he basically buys a new car every year from them and complained when they gave him bad service when trying to buy one.
So you could try some hard haggling / complaining about bad service or deals other dealers are willing to offer and get much lower than they are on sale for it seems.
