Thoroughly impressed! This was the 3rd mechanic stop for a stubborn check engine light, and true to Sam's confident promise, they were the last. They shuffled things around to get me in for a same day diagnosis, which took them a whole 10 minutes. The issue was too complicated for a quick fix, so I had to bring it back. However, they worked out a way to let me pre-pay for the repair so I didn't have to worry about being there to drop off or pick up. Work was completed for under the estimate. It passed emissions with flying colors. Though that is probably more than anyone could ask for, they also explained everything that was wrong, and used terms non-mechanically inclined females can understand. That takes time and some patience, and is greatly appreciated. I will definitely use them again; though I hope it isn't for a while.
