I went through this when I purchased my 2021 RST at the end of February. Before I went to the dealership, I wrote out a budget for the purchase based on their advertised internet price. The dealer had a $999 add on protection package that was not listed on their website. When the sales manager told me I had to pay it, I said that puts it over my budget. I then got up to leave. The sales manger then said we will take it off. I do not believe they would do that today.
