Regular price $0

When eBay Motors first appeared in 2000, no one could have predicted that online automobile sales would transform the hobby, but by the time that the innovative platform sold its 2 millionth vehicle in 2006, people began to take notice. The following year, Randy Nonnenberg launched Bring a Trailer, a website dedicated to talking about the most interesting cars offered for sale on various sites around the world. The company launched its own auction site in 2014 and has since built an enthusiastic community of more than 700,000 individuals who support the sale of almost $1 billion worth of vehicles each year. Spawning a host of imitators, online auctions are now an established part of the collector car marketplace, threatening to change the manner that cars are bought and sold forever. Our panel will look back at the growth of this phenomenon, assess current challenges and offer predictions for what the future will bring.

While attending college for International Finance, he stumbled upon a Facel-Vega which he bought and sold for a profit. Mark started sourcing cars for clients in Europe and discovered how much fun he was having doing it. “I never made a conscious decision to enter the car business, but by the time I graduated I was well on my way.”
Mark has an affinity for English, German and Italian sports cars, pre- and post-war classics, custom-bodied Packards, Duesenbergs and European one-off coachbuilts, as well as 1950s-era American collectibles. When you visit, you will also see Mark’s personal collection which includes the Dodge he restored as a teenager and a DKW motorcycle; one of his earliest finds.
Cars, travel, business, making deals and meeting people combine to keep the business fresh. “Business is fun when you’re doing something you love.”
