When consigning your vehicle with SG Auction we will begin to promote the sale of your vehicle immediately!

After many years of growing pains in a very difficult business, SG Auction, last fall, stepped up to a global stage on October 12 and 13 2018 and had a record-breaking auction in Winona, MN with the sale topping $2.5 million in sales. The reason for such a successful sale is due to our new, stronger marketing efforts, which include major international, national and regional automobile publications, radio and digital campaigns. All of which are promoted on the new SG Auction.net website, Facebook, Instagram and Twitter with the help of our new full time Social Media expert! “International” you ask? Yup…at our October 2018 sale in Winona MN, we sold a car over the internet to France! Here is what Keith Martin’s Sports Car Marketplace, a top internationally circulated publication had to say about say about our 2018 Winona, MN event: “SG Auctions is poised for continued success as an auction house worthy of attention in the Upper Midwest” We look forward to continued success working with our marketing partners in 2019!
