Back in 1975, Elvis Presley was at the height of his career and as a reward for that success, he decided to purchase this Convair 880 for an estimated $600,000 which was a significant amount of money at that time. The Convair was worth every penny according to Presley who had designed the entire interior himself and even went on to name it “Lisa Marie” after his daughter.
