Long story short, I’m looking to lease a glc300 4matic. Since it is the year end, the dealership I’m talking to said that there is no way to get what I want with all the options that I am asking for and color, so I would need to do order a 2019 model. He said that his manager will sell the 2019 for the same price as the 2018, but my question is, can I still negotiate on a ordered car?
You can, but usually you will not get much of a discount.
Is it unheard of to think I can get 10% off?
That seems extremely unlikely.
