Atlanta-Based Hennessy Auto Chain Sold To Texas Company: Founded In 1964, Hennessy Accounts For 50% Of Metro Atlanta’s Luxury Market Sales

In one of the largest retail automotive acquisitions in history for a 10-store footprint, Houston-based Group 1 Automotive (NYSE: GPI) has signed a definitive agreement to purchase the prestigious Hennessy Automobile Companies.

The blockbuster transaction is valued at approximately $1.3 billion, a figure that includes all operating assets, valuable real estate, and blue-sky value.

The 1964 Start-Up

• The Origin: The business was founded in Atlanta in 1964.
• The First Store: The family initially built their reputation around Hennessy Cadillac.
• Early Focus: The company established itself early on by focusing intensely on customer retention, high-end vehicle servicing, and the premium luxury market.

Hennessy’s Area Footprint

• The Regional Market: Metro Atlanta boasts the highest luxury vehicle market share in the entire Southeast region at 21%.
• Hennessy’s Luxury Grip: Hennessy captures roughly half (50%) of all sales in the region for its primary premium badges (Lexus, Jaguar Land Rover, and Porsche).
• Volume Metrics: The 10 acquired rooftops combined to sell approximately 22,000 new and used vehicles in 2025.

A Massive Expansion in the Luxury Sector

The acquisition represents a aggressive push into the high-margin luxury segment for Group 1. Hennessy Automobile Companies has long been an Atlanta staple, known for its premium brand portfolio. Roughly 75% of Hennessy’s total revenue is generated by top-tier luxury brands, including:

• Porsche
• Lexus
• Land Rover
• Jaguar
• Cadillac

The transaction includes 10 dealerships across the metro Atlanta area, alongside a dedicated collision center. The operation features 500 service bays staffed by approximately 280 highly trained technicians, adding a massive service and parts revenue stream to Group 1’s portfolio.

Atlanta Becomes a Primary Hub

This deal fundamentally shifts Group 1’s geographical footprint. Combined with the company’s recent regional acquisitions—including Stone Mountain Honda and Stone Mountain Toyota—this purchase expands Group 1’s Atlanta presence from just three locations to 15 total dealerships.

With this sudden injection of volume, metro Atlanta officially becomes Group 1 Automotive’s second-largest market by total revenue.

Looking Ahead

The deal is subject to standard regulatory hurdles, including customary closing conditions and individual manufacturer approvals. Both parties currently expect the transaction to officially close by the end of 2026.

Until the close, Hennessy dealerships will continue standard operations under current management.
