Diamond G: A driver's best friend

Feb 27, 2023 10:02AM ● By Arlyn Macdonald

When Dennis Goodhue first opened Diamond G Auto Repair in 1985, he committed to providing customers with exceptional service by honest and highly trained technicians.

This promise has served him well, as the shop’s reputation for quality service and customer care has caused it to grow into one of the best auto repair services in the area. 

Located on the south end of Montrose at 65790 Racine Road, the full-service shop sits on a portion of Goodhue’s still-operational family farm.

“In the early days, farmers couldn’t afford to take their equipment in for repairs, so their families repaired them during the winter,” said Goodhue, who took an interest in mechanics and started repairing farm equipment at a young age. 

In 1985, Goodhue opened his first shop in his parents’ two-car garage. Ten years later, it moved to a larger Quonset building just behind the garage, and in 2010, he built his own service building. Diamond G will soon double the number of vehicle bays, which will allow his technicians to work on more vehicles, including school buses (the shop is CDE-certified) and even ground equipment for one of the airlines at Montrose Regional Airport.


Goodhue emphasized the importance of continuing education for his current staff. Diamond G’s auto technicians receive ongoing training so they can repair newer models of cars as well as older ones. They work on minivans and work trucks; medium- and light-duty diesels; Asian imports; as well as domestic vehicles. 

“We work on most everything,” said Goodhue. “We are not a specialist on one type of car.”

Goodhue and his staff are also continually adapting their trade as new hybrid and electric vehicles come on the market. Currently, they can service many hybrid vehicles, but are not yet certified to work on fully electric vehicles. 

“In 1976, there were about 15 models of cars from four to six manufacturers,” said Goodhue. “Now there are all of these models, plus new ones every year.”  

Diamond G does all factory recommended services from oil changes to replacing belts and hoses. They also service brakes and rotors, transmission, wheels and tires, heating and air-conditioning systems, and more. 

As a NAPA AutoCare facility, all repairs and parts are guaranteed for 12 months or 24,000 miles. 

“We are honest—not perfect—but we stand by our work,” said Goodhue.

Every vehicle they work on comes with a free inspection. Diamond G service advisors take time to explain problems to each customer and make sure they understand what needs to be done before repairs are made. 



BEACON readers have selected Diamond G Auto Repair as the Best Auto Repair Shop in Montrose and Delta Counties for the past two years because of their exceptional customer service and quality work.
