At the very end of the movie when "Edward" drives up standing up in the limo out of the moon roof to come rescue "Vivan". Notice the Limo is now white, has a moon roof, and much longer than the original hotel limo they were driving around in during the rest of the movie. The limo from the hotel was always shown in grey, had the traditional wing in the back, and is much shorter. He leaves the hotel directly in the normal limo, stops buys flowers, then appears coming down the street in this much longer limo with a moon roof. What happened?
