Is this for an emergency response vehicle?

Hi, rocksing. You may get more responses if you post this over in the automotive section.

Just sayin’.

I am aware that items can be added at the time of the car’s purchase at a discount or to sweeten the deal.

But I was wanting to purchase some accessories specific to the vehicle, so I am needing to purchase through a dealership’s parts department.

Can their prices be haggled? Are the ‘official’ car accessories a fixed price at any dealership?
