Great service and honesty. My Corolla had an error code for oxygen sensor and when it was replaced, it really did not fix the issue for which it was a rare issue in cold weather and a leaky intake gasket was to blame. Stellar reimbursed me the difference in cost (as if they never had to replace the O2 sensor) but kept the new O2 sensor in the car.
Over and above workmanship! I highly recommend them to anyone with a Toyota or Lexus.
