John's Complete Auto Service is located in downtown Wauconda at Rte. 176 (Liberty St.) & Main St. Family owned and operated since 1978, our approach is straight-forward and honest. We repair your vehicle right the first time and we will have you back on the road quickly. Here at John's, we know that you depend on your car and can't afford to have it break down. That is why we use the highest quality materials and include a vehicle safety inspection on all cars. Our job is to identify and avoid potential mechanical problems, while working to keep your car running like the day it rolled off the showroom floor.
