I want to say I have been coming to this location for
I want to say I have been coming to this location for over 20+ years & the day I brought my truck in for service, I was not able to get taken care of & had to go elsewhere to get my truck worked on. I was asked for a review which I gave expressing I was unhappy about my experience. A few days later I got a response from David Marti Jr who asked I contact him to find a resolution & I did. Let me tell you, David took control of the situation & provided me with excellent service & kept in contact with me during the process. It was refreshing to have someone step up & provide good old school service & kept on it until it was done. I hope Group Auto takes care of him because he's the kind of guy you can build your business around & keep folks coming back. I was very Pleased with Mr. Marti's efforts & professionalism. I will certainly be back as a customer. Thanks Danny Maeker

Everything was done quickly and with great attention to detail, and he took the time to make sure everything was in perfect condition before handing the car back.
