Their integrity has made me a longtime customer.
I started using Hans Art Automotive 12 or 15 years ago because of a word-of-mouth referral. I had heard that they were honest and did a really thorough job. I had a very positive first experience with them and have been using them ever since.
The major thing that keeps me going back to Hans is their honesty. I never got the impression that they were trying to add unnecessary costs to the service, whereas other shops I have used have tried to inflate the bill. At Hans Art Automotive, they tell you what really needs to be done on the car and what can wait, which I appreciate.
They also are really good about keeping you up-to-date on what is happening with the car and they will call you if there are any problems. They are upfront, friendly mechanics who do not talk down to you when discussing the car issues. Even though I recently moved quite a ways from their shop, I still take my car to Hans.
