tell them youll pay cost + 10% + tax on the accessories you want
warning … this will also piss them off to no end , because dealerships have this idea that if they dont sell parts at FULL msrp, they aere somehow loosing money on the sale … as in spending MORTE then u are paying
when i worked at schmitts i sold A DOZEN audi spoilers in one week on ebay and the day i went in to start ordering them thru parts, Tim schmitt found out … he asked WTF i thought i was doing … i told him “it took me a day to make as much money for the dealership on spoilers as parts does in a year” … seriously, that year we sold ONE spoiler
he went into a big rant that selling the spoilers at the discount i was was actualy causing the dealership money oh shipping and payroll and commission blah blah blah
to bad norm was doing the ordering when he was off the clock for me, and he wasnt on commision either …
