Well, assuming the wikipediacs got it right, Elvis' Pink Cadillac page.
On July 5, 1955, Elvis purchased a new Cadillac Fleetwood Series 60 in blue with a black roof. Having mentioned a Pink Cadillac in the song Baby, Let's Play House, the first song recorded by Elvis to appear on a national chart which made #5 on the Billboard Country Singles chart in July 1955; Elvis had the car repainted by Art, a neighbour on Lamar Street. Art designed a customised pink colour for Elvis which he named "Elvis Rose," but the car kept its black roof. Once the car was finished Elvis gave it to his mother Gladys as a gift. Mrs. Gladys Presley never had a driver's license, and Elvis drove the car with the members of his band for most of 1955–1956.
On September 2, 1955, Scotty Moore drove the car into a vehicle which was passing a pick-up truck in Texarkana, Texas, causing $1000 of damage. Having signed his contract with RCA in November 1955, in March 1956 Elvis had the upholstery replaced, the body retouched and roof painted white.
On his return from military service in Germany in 1960, Presley lent the car to his US Army buddy Joe Esposito, having bought himself a white with pink roofed 1961 Cadillac Coupe de Ville.
Darn, if I'm right I'll have to think of another question.
