I was looking to have one specific item replaced on my wife's car, because it was throwing intermittent error codes.. She had been quoted around $500 for the work by the shop which had been servicing her car up till now. I took it in on a Sat. morning, had the code confirmed, the part swapped, and was on my way in under an hour. All this, and for closer to $100. Needless to say, I am stopping here for my first estimates next time around!
