Well the dealers called me today & told me they were ''very sorry'' it was there mistake & not to worry as everything is sorted.
Reason it was showing as still being for sale is they use an agency for there advertising & they had closed over christmas so no one to remove the advert off some of the other sites the advertise on.
Dealer told me the phone has not stoped ringing for the car,good job i got in when i did.
Again thanks for the good advice.
