My buddy sent me this pic asking about this tach. It was in the truck of an old car he bought. I want it but we don't know what it's worth as ebay isn't really a good place to answer these type questions. I'd like to give him 100 or 200 hundy for it. Looks like its new in the box. What should I give him for it so he doesn't put it on ebay. What say y'all?
