Hi, my name is Peter Polanski, and I am one of the Sales Consultants at Mercedes-Benz.  I was born and raised in Poland, and came to America at 11 years old, so I am fluent in Polish.

Outside of work I enjoy being active; kayaking, soccer and playing semi-professional paintball are a few of my favorites.  I also enjoy photography, go-karting, and driving AMG® vehicles on the track. I like to cook, have a good cigar, and spend time with friends and family. 

It's great to work for such a warm and reputable company as Knauz.  I appreciate all the different makes that we offer and enjoy educating our customers on all of the products Mercedes-Benz has so offer!
