I stopped in without an appointment today because I suspected my battery was going bad. Although the technician was helping another customer, he smiled and acknowledged me and said "thanks for your patience." Wow, great customer service right off the bat.
My battery did test bad, but since I bought it 4 years ago from the same Sears I got a long life out of it! It was easy to trust the shop to recommend and install another one. The tech was friendly and knowledgeable, seemed like he had a passion for cars and/or his job. I was out the door in less than an hour (despite the 3 other customers they were also helping.)
