It should be a steal since it someone's uncompleted project.  Usually parts are worth about $0.25 on the dollar.  The biggest thing is knowing exactly what you are looking at and what all is there since the car was taken apart by someone else.  Coupes aren't really my thing, but for someone who wants one I'd say its potentially a good buy at anything under $8,000 provided it is what he says it is and it has all the parts he says it does.
