I can see where it would be nice to have. My local library keeps them, they get one every so many years. If I need one I just stop in. Just a thought if you don't need it every day, plus they may have something more current.
Bought one . It wasn't very useful. I thought it would give me more info but it was more about body, bumper and some smaller parts. I sold mine on ebay. I would go check one out first.
