This mechanic shop is high-quality. Their quality is evident from the first time you get anything done there, even something very basic. I have been to other shops to do emissions testing, and those other shops seem to think that because its a simple, quick procedure they do not need to perform good customer service and that their reputation won't be affected. KLM is better than that, great service from the start. I felt confident asking for their 12-point inspection after my emission testing, something I typically only do myself (i'm a do-it-yourself person). Their report of the inspection was honest and they did not pressure me to get extra services on the spot. I will use KLM in the future for quality work, and all Marietta residents should, too.
