anyone on here that knows about stolen recovered cars?

i ask because i went to see a mk5 escort he dident have any vin number on front of car and also no ground off chassis number, he said the car is stolen recovered.

i thought somethink seems not right?

he did say theres a number stamped under bonnet to say its stolen reovered the number begings with : Sabt0329xxxxxxx

does anyone know if they stamp under the bonnect when they are stolen recovered? or what that number mean?

i even phoned dvla and gave them the reg but thay say theres no police traces on the vehical so the registration seems to check out with dvla? however i asked them about the staped number under bonnect and they wouldent disscuss that they said they cant tell me any more info

anyone advize please?

thanks
