Toyota RAV4

on October 17

William was prompt—early, even—polite, thorough, reassuring, and extremely professional. While I waited for my battery to be fixed, I benefitted from a brief but comprehensive lesson about the mechanical engineering forces at work in my car, what was and was not happening before and after my old battery was replaced, and told what to watch for/keep an eye on before driving home for winter break. I really appreciate how quick but detail oriented his work appeared to be; time and deadlines carry a special connotation of stress for me as a college student. I feel that I may be unable to appropriately convey much gratitude for the outstanding degree and quality of service I received on my car from William. Please share my feedback with him and promote/give him as much business as he can comfortably do, because this is precisely the type of employee I would imagine an employer of car repairmen/mechanics/technicians would seek in the hiring process. I fully intend to rehire your company, preferably having William work on my car, for my future automotive needs. Thank you.
