I would walk in, find the sales manager, give him a certified check for ~$28,000. If the manager doesn't accept that then start adding $100, one bill at a time from an obviously large stack, telling the manager that you already know, have already decided, when you will stop and if you get to that point before the manager flinches, accepts the current "offer", you will pick up ALL your "marbles" and go home.
Did you check who those 3 owners are? It is a bit unsual to have that many owners for a new model. May be 3 owners are, the first real owner, Lexus Toyota's agent who bought back from the first owner, and the agent who is selling it now.
