Fairmount Auto Service owner John Wansick says he doesn't do any advertising whatsoever, and his business is booming. He attributes it to word-of-mouth recommendations of his loyal customers, honest and reasonable auto repair work and the prime location of his shop, across from the El Cerrito Plaza and El Cerrito Plaza BART station. He's been in business for 35 years and at the present location for the past ten years. And Wansick also has a special employee, a friendly dog who makes the rounds with customers.
