My sentiments exactly. They also don't take into consideration the cost of
tools, test equipment, and specialty items needed to work on today's motors
that a mechanic has to buy.

That is one frustrating thing about all of these computer controlled
engines. (cars and boats) If the manufacturers had used some kind of
standard interface for the diagnostic port there would be a lot less
you would need to look at the logs and error codes.
I guess that is how they make you go back to the dealer.
Even back in the olden days with the original GM computers they had a
"one wire" serial port for the data stream but they used a strange
protocol that you couldn't see on a PC async port. There were some IBM
guys who had cracked the code but they still couldn't use a regular
serial card to read it.

I think it's a deal with "snap-a-long" so they could sell you the
reader and seperate cards for every other car
