but it's now been higlighted as a hpi'd car, so someone will know that it's hooky
all they need to do is tell the dvla who will tell plod who will inform the legal owners of it etc etc

happened to a mate of mine who bought a car and then 3 weeks later plod came round and took it away, there was only £300 on it but he didn't get it back
another mate got stung for nealry £4k years back, again, if you give money to someone who sells you stuff that they don't own, the rightfull owner just comes and collects it
