MINI dealerships near me (Mission, KS)

Dealer charging $695 for a “coating” on a 9yr old Toyota avalon vehicle is insane and the dealership already applied the coating without letting me know until after the fact. With financing being 10-12% and I’m offering cash to the sales agent/dealership. However, the sales agent is not working with me at all past a fair cash price I offered for this vehicle, it’s unfortunate. People are going to roll their heads with financing rates at the current rate of 10-12% average and vehicles sitting on the lots a lot longer, especially for a 9year old vehicle and a $695 “coating” they apply to their vehicles. At this point I would not recommend Baron BMW. Hoping to hear back from the sales agent to make things right. Like
