Well, the repair is done. After we dropped it off, I knew the damage was bad. I barely got it parked in the lot before it died, so an engine transplant was on my radar as a possibility. My guess is that the engine sensors kicked a code because the engine was starting to go. So, the diagnosis by Paul's and the cost was pretty much what I figured it to be, so no surprises there. It was done on the date promised and it seems to be running well, so that's good so far.
I have no problem on the business side of things, however, I found Paul to be abrasive and condescending. There are two reasons why I hate dealing with auto shops...they try to talk you into other things (typical of places like Belle Tire) and they treat you like you're an idiot. While Paul didn't try to talk me into anything else, I felt very uncomfortable that he brought to my attention how incompetent my husband is at every stage of the repair. Will I return...don't know. I guess it depends on if the quality of the work outweighs my personal offense to his attitude when I need a repair shop again.
