Do not pay the Dealer Delivery if the Dealer cannot provide you with an itemised account i.e. listing ALL input by them added up to exactly match the amount they are asking. It is a rip off and used by dealers to offer new price discount etc. I have never known a dealer to provide such information, they will often back down on seeking such payment - it is not legally required that a purchaser should pay it. It is not a requirement of the manufacturer. It is a fee introduced by dealers who managed to get away with it particularly with corporate buyers who paid what was on the invoice. Originally (back in the 1960's) it was charged to provide aluminium embossed plates, a key ring with the stealers name embossed and a tank of petrol. Customers thought they were getting something for nothing !!!
Good luck.They will give you $1000 discount if you pay the $2,000 stealer delivery impost.
