I have a London zone 1 flat . Yesterday morning I tried to park my car there in our underground car park in my numbered spot and it was occupied . The entry is by key fob which operates an automatic garage door and the 24 hour concierge don’t know whose car it is. They didn’t see it come in. One possibility is that it tailgated another resident. It may or may not be stolen. Parking here is about £30 a day if I can even find a space and there is congestion charge as well. I’ve looked on google and it seems We cannot get DVLA or police to tell us who owner is quickly. DVLA is a form by post. We cannot get help from council as it’s a private garage . We cannot get it removed . What can we do ?
