Merchant Automotive, LLC was founded in 2004 by Eric Merchant. Eric was a long time employee of GM dealerships before forming Merchant Automotive, LLC. Eric got his start in high school where he discovered his passion for anything with a motor. He took his passion and turned it into a career in 1993 working in a small shop doing brakes and alignment work. He accumulated knowledge daily and soon took a position at a GM dealership in 1995 and advanced up the ranks over the next 10 years. Along the way, Eric studied the business hard, taking over 3000 hours of GM training and maintaining ASE Master Certification since 1998.
In April 2008, Merchant Automotive moved into its current location in Zeeland, MI. The move was a huge undertaking that involved a complete remodel of the building. That building, having over 10,000 sq ft of space, has allowed for greater expansion and a large retail front.
