Auto Dealers Shift to Service and Finance as New Car Profit Margins Shrink

The automotive retail landscape is undergoing a fundamental transformation, as dealerships strategically pivot toward their service bays and finance offices to safeguard profitability against volatile new car sales. This shift underscores the industry's resilient, "hedged" business model, where high-margin backend operations provide a critical buffer. Historically, dealerships have operated on four core profit streams, but the balance of power is changing. According to Erin Kerrigan of Kerrigan Advisors, the economics are starkly clear: for every $10 lost in new vehicle revenue, only $1 in service revenue is needed to maintain gross margin, thanks to service margins of approximately 50% compared to just 5% for new cars. This dynamic insulated dealers during the 2008 financial crisis and fueled record profits during the pandemic's supply-driven boom. However, with new car profits now receding—falling from an average of $6.8 million per dealership in 2022 to about $3.9 million in 2025—the backend business has become the primary engine. Concurrently, finance and insurance (F&I) products have proven to be a remarkably stable profit center, often constituting nearly a quarter of gross profit for major publicly traded groups. This strategic reliance, however, is not without its challenges. The service and repair market is becoming fiercely competitive. A Cox Automotive report reveals dealers' share of service visits declined from 33% in 2017 to 29% in 2025, while a Ducker Carlisle study found the share of consumers naming chain service centers as their primary provider surged from 20% to 42% in the five years to 2025. This 22-point swing indicates a significant consumer shift, often driven by perceptions of higher dealer pricing—a notion the industry is actively working to dispel. "They are taking great effort to... try to become more competitive on pricing," notes Seaport Research Partners analyst Glenn Chin. Ultimately, the modern dealership is being reshaped by this financial imperative. As Jeff Lick of Stephens points to a "K-shaped" economy in auto sales, where demand for necessity vehicles outpaces "want-based" luxury models, dealers are doubling down on the consistent, high-margin revenue from owners maintaining their vehicles. The industry's future profitability hinges not just on selling cars, but on successfully retaining customers for their entire ownership lifecycle through competitive service and valuable F&I products.
