Definitely technical, not restoration.
I have put this off as long as I can. Getting too many late model cars in the family, and would like to be able to read codes without leaving the driveway. I had a Cadillac DTS for a while and was spoiled by the self diagnosis.
I noticed some of the really cheap ones don't read Toyota. We still have one Toyota in the family (other one was rear ended last week). I was looking at this one on ebay:

Must be able to read Ford, BMW, Toyota, Infiniti.
Any comments? Suggestions? What are you guys using?
