What Our Customers Are Saying

I cracked a cylinder head in my engine in my beloved 4Runner after initially thinking it was just a clamp accidentally left on my fuel line after a smog check elsewhere. Mike is so honest and his prices are so fair and reasonable and he even gave me a ride home and dropped me off. He also straightened out my license plate for free. What a guy!!!


-Heidi T.

This is the best place to take your vehicle for repairs. Mike is a straight shooter and made the process of dealing with my warranty company very simple and stress free. He was very responsive and kept me well informed throughout the process. I strongly recommend this place for any auto repairs you need!


-John L.

My wife and I have been taking our vehicles to Mike at Giant Oak Automotive for over 20 years. During that time Mike and his crew have consistently provided excellent service at very fair prices. He is honest, hard-working, knowledgeable, and will go the extra mile to get the job done, often without charging extra. I would recommend his shop without hesitation for anyone needing a reliable mechanic.


-Bill S.

Excellent service and the person that helped me was so helpful and honest. I will be going back to this mechanic from now on. Thank you for your help and for easing my mind by taking good care of me and my car.


-Olson R.

I did my homework...received quotes from two other local shops. I ended up here and what a great decision that was. Mike is such a great guy! His prices are more than fair and work and work ethics A+. Come to find out, my two brothers and nephew already use Giant Oak as their go to mechanic. You know the feeling when you really know you have found an honest mechanic...This is the place and Mike is the man!


-Rick S.

Best place in the world. Mike is a gem, honest, knowledgeable and a hellava,nice guy. This is the place for your car, they will not sell or fix anything that doesn't need fixing. Just like the old days, good price, great work.


-Lee J.

This is definitely an overdue review. A few months ago, my car battery was on the fritz. Giant Oak Automotive accommodated by schedule for same-day service, diagnosed the problem, and sold me a high-quality battery. Since that time, I have gone back to Giant Oak Automotive for preventative maintenance (e.g. oil changes), and have been very happy with the company's professionalism and customer service.


-Rachel A.

Mike is a great guy, does great work, and is very conservative with his treatment of your car. He doesn't take chances, and always looks out for your best interest. I trust him completely, and have been taking my cars to him for at least 15 years.


-Rob L.

Mike at Giant Oak Automotive was a huge help. We had a client in his area with a noisy belt and he was able to take care of it quickly.


-Nick M.

Love the owner, him and his team do great work.


-Tarrant R.

Very knowledgeable and reasonable. Love the way they take care of our cars.
