My 2002 Silverado would not pass inspection because of the engine knock sensor (questionable design by GM). After doing my home work on prices to fix this, I came to find the service writer Jonathan & the service technician at Automotive Specialists knew what was going on with my truck. Futhermore, they were very knowledgeable on how to prevent this from happening again. This may not impress many, but the two dealerships I called did not have a clue as to what I was talking about.
Pros: Set your mind at ease.
