Gary Eschen runs a terrific family business on Seattle's Eastside specializing in Japanese cars.
He and his staff have helped me over the years with our Accord and Civic. Always good at explaining things. Business ethics are all about communication, fairness, honesty, and above all -- technical competence!
They can't always answer the phone; most of the time they do but they're a small shop so they have to actually work on cars. They always call you back when they get to a place in the process where you have to make a decision; they're also very good about discussing intelligently car problems and solutions over the phone and they're good about returning calls.
You can drop off your car after hours.
