there was a thread on here a while back where bankers drafts aint actually guarenteed money any more,
as for checks hip will only bring up recoreded history, if the car has history but not recorded then it wont show, if you can or know somebody in the trade ask them to come along, main thing is to check for overspray on rubber, panels not fitting right, bothced interior of repairs, if it looks like a dog then it will be, if its priced to cheap then theres a reason to,
