Sales to RDS Automotive Group and Piazza Auto Group highlight strong buyer demand for established General Motors dealerships in desirable metropolitan markets.
Fort Lauderdale, Fla., November 9, 2026 — Haig Partners LLC, a leading buy-sell advisory firm to auto retailers, served as the exclusive sell-side advisor to the Hill family on the sale of Hill Buick GMC to RDS Automotive Group and Hill Cadillac to Piazza Auto Group. Both dealerships are located in Newtown Square, Pennsylvania, a desirable suburb of Philadelphia. The transactions followed a competitive sale process that attracted significant interest from qualified buyers.
For 35 years, the Hill family has owned and operated its dealerships along West Chester Pike in Newtown Square, building a reputation for exceptional customer service, strong performance and deep community relationships throughout Philadelphia’s Main Line and surrounding Delaware and Chester Counties.
Hill Cadillac, led by Geoffrey Hill Sr. and Randy Hill, has earned multiple Cadillac Master Dealer Awards and is the Escalade retail sales leader for Cadillac in Pennsylvania. Hill Buick GMC, led by Geoffrey Hill Jr., has been recognized as a Dealer of the Year for five consecutive years and maintains a 5.0-star rating. Together, the dealerships represent a successful multigenerational family business built on decades of hands-on ownership and a commitment to its customers and employees.
“These dealerships have been a huge part of our family’s lives for more than three decades, so deciding to sell was about much more than finding a buyer,” said Geoffrey Hill Jr., President of Hill Buick GMC. “Derek Garber and the team at Haig Partners took the time to understand our family, what we had built and what mattered most to us. They brought tremendous knowledge of the market, created strong interest from qualified buyers and helped us navigate the process with confidence. We couldn’t be happier with the outcome. I want to congratulate Robert DiStanislao and RDS Automotive Group, along with Dan Piazza and Piazza Auto Group. Both are outstanding operators, and I know our employees and customers will be in great hands.”
“Having worked with dealership owners throughout Pennsylvania and the Northeast for years, I’ve seen firsthand how much value buyers place on businesses with strong operations, loyal customers and an established reputation in their communities,” said Derek Garber, Managing Director at Haig Partners. “The Hill dealerships checked every one of those boxes, and the level of interest we generated reinforced just how competitive the market remains for high-quality General Motors franchises. What made this transaction especially rewarding was working with a family that had spent 35 years building something special. Our job wasn’t simply finding the highest offer. It was to help the Hill family understand their options, maximize the value of what they had built and identify buyers they felt confident entrusting with their legacy.”
The dealerships were acquired by two established automotive retail groups in the Philadelphia market. RDS Automotive Group, led by Robert DiStanislao, is a premium automotive group headquartered in Newtown Square. Piazza Auto Group, led by Dan Piazza, Esq., is one of the Delaware Valley’s largest automotive retail organizations.
The transactions reflect a broader trend in the dealership buy-sell market, as well-capitalized buyers continue to pursue established franchises with strong market positions, consistent operating performance and meaningful fixed operations businesses. While acquisition strategies have become increasingly selective, dealerships with proven management teams, longstanding customer relationships and attractive locations continue to generate substantial interest. The competitive process for the Hill dealerships demonstrates that quality domestic franchises remain highly sought-after assets, particularly in major metropolitan markets.
With this transaction, Haig Partners has advised on the sale of 23 dealerships throughout Pennsylvania, further demonstrating the firm’s extensive experience and relationships across the Northeast automotive retail market.
Assisting the Hill family in the transactions were Paul Marshall Harris and Sarah Judge of ArentFox Schiff and Robert Salad of Cooper Levenson, providing legal services. RDS Automotive Group was represented by Michael Menkowitz and Gabriel Herman of Fox Rothschild. Piazza Auto Group was represented by Steven Hanford of Silverang, Rosenzweig & Haltzman, LLC.
