Daryn's Approach
You won't find personal attention quite like this anywhere else. At other shops, you may find an employee tasked with answering the phones or scheduling, a service writer, a mechanic, a supervisor, and a front desk employee. At Cel Automotive & Diesel Repair, Inc. Daryn takes care of you and your vehicle from start to finish - there is no middle man or message relaying. When you have a question about a price, an appointment, a concern about a noise your vehicle is making, or something that was done to your vehicle Daryn will be there to answer it. There are no dreams of expanding the business. It's simple; Daryn loves his job, he's good at it, and you can trust him. Cel Auto continues to have an excellent reputation in the Billings Community for honesty, work ethic, and auto knowledge.
