I go to Stillwater Automotive because I always get an honest straight forward answer and my problems are always solved. I can not say enough about the quality of service I receive. Thank you Stillwater Automotive!Todd D.
Vadnais Heights, MNI like doing business with Happy’s because they’re courteous, professional, honest and locally owned. However the main reason I’ve been bringing my vehicles to Stillwater Automotive Diagnostic Center is because in six years of routine maintenance and some major repairs, I’ve never had to bring a vehicle back because a repair was performed poorly. That’s critically important to people like me who depend on their vehicle to generate income.

I have been a customer of Stillwater Automotive Diagnostic Center ever since they opened 14 years ago. We have 4 cars in our busy family, and the last thing that I need is an unnecessary breakdown. The people at SADS know me and they know my vehicles. I don’t know much about cars, so the staff at Happy’s are very good at advising or recommending to me what needs to be done in order to keep my cars running without interruption. Over the years, I have developed a strong trust in Stillwater Automotive Diagnostic Center, both in the recommendations and actual work completed. I stop in on many occasions just to ask questions. I have also have had instances where I brought a car in for work that I thought needed to be done, and they have actually advised me that the work wasn’t necessary, either by checking the previous service record that they keep tract of, or that the work could wait until a later mileage date. I am not sure that this would happen at repair service that doesn’t know me…

Finding a good, reliable and honest mechanic is hard to do these days. However, we have found just that at Happy’s Diagnostic Center. We have been a customer for 10 years and have taken a variety of different vehicles in for service. We have been satisfied with each and every visit that we have made throughout the years. Your work is top notch and we would highly recommend you to all our family and friends and everyone who is looking for quality work and high moral character!…
