When I shopped for my old wrangler I started calling dealers and told them I had supplier pricing and was looking for a dealer to beat it. Most brushed me off but one called me back and said no problem, we can do it. Sure enough I talked to them, they were very helpful and I ended up buying it. Just reach out, be honest and see what they say. Some will come back with BS but you’ll pick it up right away but many know if you have supplier pricing you don’t want back and forth BS so they cut to the chase and tell you no or tell you what they can do.
