If it was the same dealer, or at least if your local dealer is within the same dealer network, then there may be the option to discuss discounted servicing.
Once you have negotiated a price then try and get some extras, such as new mats or an updated sat nav map etc. Don't start there otherwise they won't lower the price.
They will probably be resistant to lowering the sticker price, stating that the vehicles are rare. However that works the other way too, dealers are often stuck with IS Fs for months with its book value dropping every week.
