Efficient, professional, and friendly

As a middle-aged, single female who drives an older car, and who has also moved around a lot, I have spent hours and hours researching mechanics ... reading reviews, asking neighbors, calling the shop itself to ask questions. Now that I will be here long term, I am so happy that I won't have to go through that process anymore as I am happy to have found my go-to auto repair shop, which is Tanner Motors. They are professional, knowledgable, approachable, courteous ... I can't even think of anything else I could ask for. The shuttle service they provide is so considerate. AND even though they aren't a VW shop, they have my '03 VW running better than ever. Thank you guys so much for taking the extra time to answer questions / explain issues and to ensure my car is running so well. Even though it's old, you treated it as importantly as if it were a new ride that I needed for work. THANKS AGAIN!!!
