John Walker's Workshop in the Greenwood area of Seattle is a Porsche service facility of the highest caliber. John started working on VW's in 1968, Porsches in 1975, and opened his first Greenwood Avenue shop in 1980. John's first love is working on 911's but many of his steady customers drive other models of Porsches. At this workshop the man you talk to is the man who does the work, John Walker. There is nothing lost from service advisor to mechanic. The system works because John's repeat customer base has been growing steadily every year. The shop includes three hoists and bays for six cars, plus all the necessary equipment to do any job right. And cars left overnight will be parked inside.
