So I got the van back on Wednesday. Overall I am happy with the labor rate(roughly $120/hr) and cost of parts, no complaints there. It looks as if they did everything that I had asked for (and threw in a free tire rotation), and the price ended up being $1000 not $1400, so I am also extremely happy about that.
The only down side was the pre-purchase inspection, and I think I can take some of the blame here, but not all. They only charged $90 for the inspection so I don't think I can expect an inspection anywhere near the level described by carringb.(and I think my mistake was asking for a pre purchase style inpsection I think I should have clarified what I was looking for better) If they are charging roughly $120/hr for labor and only charged $90 for a pre purchase inspection, I can only assume it was mostly a visual inspection which seems a little worthless on a van since everything is pretty well tucked away. Especially considering that this is what my air filters look like and they didn't mention it needing to be changed at all:
I don't think the picture does justice to the dirt that is on the filter. I would think that anyone that lifted the airbox cover would have flagged it on an inspection report, but that was not the case. This makes me concerned that the inspection wasn't really worth much.
Overall I am happy and will take the van back for jobs that are bigger than I want to tackle.
Here is a copy of the work completed, like I said final bill came to $1000.
