Aiea, HI ("Pearlridge")
Doesn't look fancy, but a lot of thought was put into the shop setup and customer service! I was in dire need of urgent maintenance (uneven tire pressures + 115 miles past due maintenance date) and they accepted me as a walk-in anyway. As all car-related services go, they know that services can be unpredictably long and inconvenient, so their waiting area was equipped with lots of space, decent free WiFi, and cubicles for people to study/work and charge. Cherry on top: when they were done servicing my car, the staff (Charlie + two other guys I didn't get the name of; sorry!) were super accommodating and friendly. Even let me refund my service just to help me charge the correct credit card - they earn 2x miles for Hawaiian & Alaskan airlines! Great service overall, would recommend.
