I'd agree that there must be some room in that price. If the OP likes the car...I'd suggest trying to work with the dealer. Then again, I'm one that says the definition of a good deal is when both parties agree.
In reading this thread, I do have a question. I often see folks mention that a car is a non PP car as though it's a problem. I completely understand what's in the PP package....and what you can't get if you order that package. When I ordered my '18, I wanted the features that you can't get with the PP so there was no debate for me. I guess it's just personal opinion. ( I must admit to liking the PP steering wheel although I'm not sure how it would wear over time. )
