Greenbriar-backed GB Auto Service, a premier provider of vehicle maintenance, repair, and tire replacement serving, completed the acquisition of Sun Auto, a provider of tire and automotive service facilities. Financial terms were not disclosed. "The automotive aftermarket is a key area of focus for Greenbriar due to its size, channel structure and defensive characteristics, which create a diverse set of investment opportunities. This acquisition is the twelfth for GB Auto over the last two years, and reflects the continued execution of our strategy to build the leading independent aftermarket service provider in the Western U.S. We have great respect for the business the Higginbothams have built, and we are thrilled to welcome Tom and his team into the fold," Matt Burke, Greenbriar Director.
