Now the issue, we realized today only that the engine number differs from the number on the registration docs, the number on the vin plate is also different from the vin no on the registration docs. I also lost the vin plate (I only have a photo) as it was given to me loose and was not attached to the vehicle. The guy who did the "restoration" is ignoring me, he started working under a new name. I do have all correspondence between us, invoices, POP's and an affadavit from him, stating that he sold the vehicle to me.
Any advice on how I can go about sorting this mess out, as the buyer is still keen, provided the vin and paperwork is sorted out.
