Why don't you try a dealer for a long shot as they have temp cover in which they gave me when buying the car..........
What it was, they were waiting on my private reg plate to transfer onto the new car via the DVLA. So after I arranged for my private reg to be placed on my new car the DVLA returned my log book without the transferal...... The only option was then for the garage to place my new car onto their cover for a week............... until my transfer was complete...........
