A Premier Automotive Core Supplier

Buffalo Core Supply is a 3rd generation full-line automotive core supplier and core buyer. Our primary warehouse is located in Buffalo, New York.

You may remember us as M&M Knopf or Knopf Automotive. Our name has changed, but our mission hasn't.

We have accrued 70 years of knowledge, experience, and contacts in the automotive core industry. Only now, we are bringing our family automotive core supply business into the 21st century.

We have developed a web-based app to show our core supply vendors our buy-guides and pricing. Once you become a registered automotive core supply vendor, you will gain access to our user-friendly app. Our app allows you to view our buy-guides and lookup parts by VIN and/or application.

We have been building our systems and our name for the last three generations.  Our ID databases of OEM numbers, casting numbers, tag numbers, and photos are unrivaled in the automotive core supply industry.

The Knopf family name is one the automotive core supply industry has learned to respect and count on. Customer service, integrity, and family values are the foundations upon which our automotive recycling business has been built.  Our commitment to excellent service to our customer base and core supply vendors has been unwavering for the last 70 years!

We look forward to forming strategic alliances to fill the consistent needs of our customers.
