You are basically getting no discount, it’s not even a reasonable starting point. If you prefer to work a deal yourself, you need to canvas a larger array of dealers, after putting together a target deal proposal. As an example, on the IX I would be asking for 12% off at base MF.
If you want the easy button, use a broker. I am sure @AutoCompanion @IAC_Scott or @AutoNinjas can beat any of these deals easily. In addition, other models you should be cross shopping are EQS and Etron, both of which are leasing well.
Then what is your trade-in?
