That dealer is freaking dumb.
My local Lexus was more than happy to take the check for the entire IS250 with a BIG grin on their face.

They even have the general manager and finance manager came out and walked with us to the car.
And when we found out that the sunroof hasn't been programmed. They call out 3 of their engineer manager to get it done.
They even offered me to traded in the G35C for their new SC430 which I smiled back and said no, I'm not that dumb.
Screw that place, go to the other one.
