They did a fantastic job diagnosing and fixing my 2005 Avalanche truck. He was fast, and also personable and friendly. He knows his stuff! We had the front suspension fixed. Thanks Denny's Auto Diagnosis.

Yelp Review

I've taken a couple different vehicles here and received fast, affordable and honest service both times. The mechanic explained everything thoroughly and gave me options on how to proceed with repairs based on the cost and extent of the repair needed compared to the value of the vehicle. I never felt misled or strung along for "extras" like some places will do. This is the type of business that wants their customers happy and rely on their satisfaction for repeat business and to spread that news by word-of-mouth. I will definitely be back for maintenance services and any repairs I might need in the future.

I had a chirp in my brakes. Took in the the vehicle to get fixed up. They had the opportunity to replace the parts and just charge me as is, but instead let me know there was still plenty of life in the parts. While they were doing the investigation, they noticed a couple other small issues that they fixed up free of charge to keep the car running smooth. If you’re looking for a honest car repair shop, this is the place to go.

Have been going here for yrs. Extremely competent and skilled mechanics. Friendly, even cheerful service. More than once they have gone the extra mile. Have been referred for specialty wrk they weren't equipped to do. However, they can handle virtually any minor to major repair. Pricing not cheap, but fair & competitive. Have proved to be completely honest & reliable. This repair shop is a first rate operation. Family owned & operated. Highly recommend them.

Honest, experienced, and remarkably personable.

My Honda Civic (known as Champagne) randomly developed a mind of her own. She developed a thirst for blood, and would drive full-speed ahead to wherever she wanted once I turned the key in her ignition. Driving her became scary and I planned on bringing her get her looked at on my day off. However, she couldn't wait, and upon starting would jump to 4500 RPMs and wouldn't come out of park.

I chose Denny's because it was local to my home, and my boyfriend had use them years ago for an older Cadillac and received great service.

I can't stress how wonderful Denny's was during the whole fiasco. Denny (the owner, who was been doing his thing for over thirty years) took extra time with me, even after hours, on the phone to get a better understanding of what I had experienced with my car and I never felt rushed or embarrassed. He gave me honest answers and competitive and fair prices. Upon completion, after research, I know Denny's saved me over $700. My car is back to her normal and even better self, and I will always chose Denny's in the future for her needs.
