It Started with a Kiss (1959) on Netflix

Air Force Sgt. Joe Fitzpatrick meets and marries a beautiful model, Maggie Putnam, on the eve of being shipped off to Spain. When the new Mrs. Fitzpatrick waits to join her husband, she promises him in a letter "the most wonderful surprise that could happen to two people." Joe naturally assumes that she's pregnant, but the surprise turns out to be a fabulous new car that he won in a raffle. His new bride and car win him the scorn and jealousy of Spain's most famous toreador, not to mention the suspicions of his commanding officer.
