Checking in for western Washington State - Seattle area.
Signature Independent has been a bit disappointing lately. I used them for five years exclusively. They have a great staff and are very knowledgeable, but the past few times through there were lots of small errors or misdiagnosis. I've spent about $2,000 on repairs they claimed I needed but turned out to be other issues entirely.
I've started going to
WestWerks and so far am very happy. Friendly, quick, did small extra bits the car needed without charging me and even drop it off at my office when they're done.
