The waiting Aston Martin DB10 was clearly a surprise for Eugenie who said “wow” and was left open-mouthed when she saw it.
Eight models were made to film the 2015 movie Spectre starring Daniel Craig, and Jack managed to get the keys to one of the coveted cars.
Eugenie first spotted the Aston Martin when the newlyweds arrived at the Equerry’s entrance at Windsor Castle to say their goodbyes.
A few minutes before they arrived, the Duke of York strode from the castle to watch the Royal Household’s transport manager Alex Garty arrive in the James Bond car and manoeuvre it into position.
Andrew joked he wanted it a few feet forward and quipped “no pressure” as Mr Garty gingerly moved the car.
When the bride tried to get into the Aston Martin the groom and Beatrice quickly realised they had to accommodate the large train of her wedding dress, designed by Peter Pilotto and Christopher De Vos.
The pair spent a few minutes folding the yards of material into the Aston Martin before carefully shutting the door.
Sarah, Duchess of York and Mike and Zara Tindall were among the wedding guests who waved the couple off as they left to prepare for their evening celebrations.
