68 Hemi Gtx

Unless $$ is no object to you, and in most cases anyway, the finders fee is only justified if a purchase takes place. Just pointing a car out in a strangers back yard doesn't warrant $500 either. For that coin, he should be able to introduce you to the owner, and he'd better be selling. If not, he's earned his $20.

Looks like an interesting car, good luck with it.
