I had John P my service rep, check my car for engine head oil leaks and was afraid of worst case scenario which would have costed a lot, they did thorough inspection and found out it was just dirt accumulation due to change of weather, they cleaned my car while they were at it and charged me only for oil change, they explained very well my next check up procedure, never had a problem with diagnosis and regular service here in tempe, keep up the good work
