Aston Martin Volante takes William and Kate to Clarence House

(CBS) Prince William and Catherine Middleton, the Duke and Duchess of Cambridge, left Buckingham Palace for Clarence House in style on Friday, driving an Aston Martin convertible covered in ribbons and balloons.

The car is an Aston Martin Volante DB6 MKII, in Seychelles blue. It belongs to the Prince of Wales, who has owned the car since 1969.

The license plate read "JU5T WED." William was in the driver's seat, with Catherine next to him.

The car was accompanied by a Search and Rescue helicopter in a special fly past. The helicopter was flown by members of 'B' Flight 22 Squadron, the same the same squadron to which William, a search-and-rescue pilot based in Anglesey, Wales, belongs..

In June 2008, the car was converted to run on E85 bioethanol, made from English wine wastage, at the Prince's request.

William and Catherine were at Buckingham Palace for a luncheon hosted by Queen Elizabeth II, which followed their wedding ceremony and subsequent wave - and kiss - on the palace balcony. The couple will return to the palace at 2 p.m. EDT (that's 7 p.m., British time) for an evening party, hosted by Prince Charles, for about 300 guests.
