$5,000 discount just for listening to ads, that you may find a way to turn off? Unlikely.

What I do think may happen is, it maybe marketed as a 'feature' with some actual perks. Such as free access to extra live GPS information (reads, advertised businesses on your map), free satellite radio/digital music where they interject these ads (basically like traditional radio, but they can monopolize), or something along those lines.

I know certain... people... who would definitely go for this if it offered live sale notifications... "*beep* 20% off on woman's footwear, 200 metres ahead on your right"

You could always have the dealer look for one that fits your preference in another location (most of them have exchange programs so they can trade a car on their lot for one in another dealer's inventory), or just order a custom build. It takes a could months, which is not long at all a wait for a purchase that you may be using for 10+ years.

I had to order a custom build when I traded my SUV in for a mini van for the growing family, because I never trusted sun roofs, and for some reason, the dealerships were convinced that "people love sun roofs". So every single one on their lot and across Canada had a sun roof.

Also, because dealers do prefer to sell car off their lot so they don't get stuck with a stale inventory, they would probably not go all out on an unpopular option, even if that makes them some extra.
