Welcome to Coulter INFINITI


In many ways, the evolution of the Coulter Automotive Group is the story of the growth and prosperity of the Greater Phoenix area. Four years after the Grand Canyon National Park was founded, C.W. Coulter became a partner in Snow and Tufts, an Oldsmobile/LaSalle dealership in central Phoenix. In 1923, the dealership was awarded the first Cadillac franchise in Arizona. By 1926, slightly more than a decade after the Arizona Territory became a state, the dealership was renamed Coulter Motor Company, forming the rock on which the firm’s reputation was founded.




The original Coulter dealership at Central Avenue and Van Buren was at the hub of the young City’s most unique and vital businesses. The Salt River Valley became known across the country as “The Valley of the Sun.” The San Carlos Hotel with its innovative air conditioning and elevators opened a block away from the original dealership, and the City’s tallest building, the Westward Ho, was its neighbor to the west. During this time of excitement and new beginnings, C.W. Coulter began laying the groundwork for the Coulter Motor Company’s culture of exceptional service. Through the boom years of the 20’s, through the Great Depression and even World War II, the Coulter family tradition of selling the highest quality automobiles backed by responsive customer service established the Coulter brand that has no equal in the Greater Phoenix Area yet today.


The next generation of the Coulter family, Dean Coulter, worked his way up from an entry position in the shop in 1933 to sole ownership of the company in 1968. He continued to expand the Coulter sales and service reputation. As the Phoenix population surged past 200,000, suburban growth moved the City’s hub northward to Camelback Road. A new location was then opened at 12th Street and Camelback Road with a huge celebration in 1971. Searchlights generally reserved for movie premiers lit up the sky over the 20-mile square Phoenix metro area, and could be seen as far away as Mesa and Glendale.

The dealership on Camelback became an instant landmark with its iconic “car on the roof.” The Coulter culture of thoughtfully treating everyone who comes through its doors with the utmost courtesy and respect includes the wide-eyed and curious of all ages who continue to ask to this day, “How do you get that car up there?”



Mr. William “Bill” Coulter is the third generation business leader to continue the tradition of unequaled service across the Coulter enterprise. As the City of Phoenix grew to cover 255 sq. miles, the Coulter Automotive Group expanded to include additional lines in the Camelback location. They have since opened the spacious Coulter Motor Company in the Tempe Autoplex off of I-10, convenient to Phoenix, Tempe, Chandler, Gilbert, Sun Lakes and Ahwatukee. A fourth dealership was established to expand the Coulter presence on the West side of the Valley to serve Phoenix, Glendale, Peoria, Avondale and Sun City. The latest Coulter luxury brand, Coulter INFINITI in Mesa, was added to extend the Coulter brand of excellence to the East Valley.

While dozens of dealerships across the State of Arizona have come and gone over the last century, the Coulter family remains successful because their culture of striving for exceptional service extends to every customer interaction. Drivers from Phoenix to Scottsdale and Tucson have come to trust Coulter with their automotive needs. This is because C.W. Coulter knew that treating his employees like family and supporting their efforts to keep the company’s service commitment always in mind was a business model that would endure. Today, Bill Coulter manages a 516-member “family” of loyal employees that carry on this simple philosophy: treat every customer with respect, provide welcoming sales and service environments, sell automobiles at a competitive price, and above all, make sure every service experience inspires trust and loyalty.



Owning an automobile is more than having a means to get from one place to another. For many, it represents a significant investment, second only to owning a home. With the advent of the Internet, comparative car shopping has reached a new level for consumers, and yet car owners are still dependent on the integrity of the dealership they choose. There is a reason why the Coulter Automotive Family of dealerships remain the choice for three and four generations of luxury car buyers.

Coulter employees are dedicated to making every customer a part of the Coulter family for their car-buying life.

We invite you to come in to a Coulter dealership and let the Coulter team show you the way the car-ownership experience is meant to be. We believe everyone deserves to enjoy the Coulter Experience.
