Any owners drive in the snow yet with the 450? It is a very heavy car and I am curious with the rear wheel drive how it has performed. The 580 is a bit more than I want to spend currently with the $40k dealer mark up.

 

It should drive in the snow, similarly to any RWD but better. Electric traction control is instantaneous. However, it's not going to be anywhere as adept as a 580.

 

If you look you will find dealers willing to give you an EQS close to MSRP. I got mine 2k over.
