Although they were neither the closest nor the least expensive shop, the preponderance of positive reviews swayed me & I set up an appointment online via Repair Pal (which gives you an idea of what cost range to expect) to have an oxygen sensor replaced and get an oil change done while I was at it. Andy was very straightforward in conversation, suggesting that while my initial diagnosis (the code, common things that go out on my type of car at this age/mileage, etc) was sound, I should probably let them diagnose it before replacing it blindly, which is a very respectful way of saying that they do this for a living and probably know a few more things than I do :-) :-)I liked Andy right away.As part of their service, they would also provide an inspection of general vehicle health. Andy offered to text it to me when they were done so I could review if there was anything that was urgent. I headed over to Seattle Urban Coffeeworks with a few episodes of Season 2 of "The Expanse" and enjoyed a very mellow morning. Inspection had several watch list items -- not unexpected for a car of this age or mileage. The thoroughness is appreciated, but what really knocks it out is the inclusion of pictures. From this, I have a better understanding on the problem and severity. Car was done shortly thereafter and I was back to work by 10. They are clearly a quality shop with top notch mechanics and great customer focus. Thanks, guys!
