Mario A Walker joins Broad Arrow Group as a Car Specialist, with over 20 years of experience working in the collector car industry. Most recently, Mario has operated as an independent collector car consultant, having curated collections for prominent clients at various levels within the automotive industry. He has previously held positions at Hemmings Motor News as a Senior Executive, at Bring a Trailer as a Specialist, and he is also an active member of SEMA's Future Leaders Network organization.

He credits his love of automobiles to his motorsports-obsessed family. Growing up, Mario spent many days trackside with his father who raced a 1973 Datsun 510 in the SCCA B-Sedan class alongside fellow gentlemen racers in the Northeast region and learning the family business of collecting and servicing enthusiast Sportscars. He possesses a broad knowledge of collector vehicles but has a particular affinity for 1960s-era sports and racing cars as well as a genuine fondness for 1990s and 2000s European and Japanese Sportscars.

Today, you will most likely find Mario at various international automotive and motoring events, and he is also an active member of several automotive clubs and organizations. A true motorsport enthusiast at heart, Mario's goal is to one day compete in the annual Rally Barbados piloting his WRC Group A homologation 1992 Nissan Pulsar GTI-R. Mario is based in Miami and travels to meet with clients throughout the world.
