At the moment you couldn't talk to the dvla even if you wanted to they're still not working.Could i ask what would everyone else do in this situation ? The guy has also left me with a suspected head gasket issue as well so got to spend on it
Tbh I wouldn't be in a hurry to confess anything to anybody........give us a pic of the dumb iron, as much as possible. You can blank out the chassis number but would be interesting to see if its either been re-stamped, re-welded, or generally had bits chopped off or welded on.
