Dealerships that have value based sales staffs that are non-commission do not sit around talking about what vehicle has the most gross, or use words like "mooch", "pounders" or "lay downs". They talk about what neat cool ways to enhance consumer experience when they contact them.
My advice is to not really worry too much about your value based propositions. Just start with some, and through communication with your staff you will improve upon them and create new one's.
Your biggest issue going One Price is to make sure you have a staff that believes in it. Starting with your sales managers. If one sales manager says one thing about "this isn't going to work", or "we would sell more cars if we negotiated" you need to fire them. Non-believers are the cancer of One Price selling and the main reason why it fails. You either are negotiation free or you're not, there isn't any wiggle room there. The first time a manager throws in a bed liner it'll start collapsing on you.
Most dealerships are one price now anyways. Depending on the make that you sell, you need to priced so competitive that there really isn't much negotiation anyways. Selling used cars priced to market should have an average move of less than $250 to make a deal.
This is why I went with a hybrid of negotiation free. It made it so I didn't need to manage the NF part and left the rest to hiring like minded people (usually with zero auto sales experience) and making sure customers experiences are differentiating with us vs the competition.
