Partridge Family Bus - Multi-colored school bus on the sitcom THE PARTRIDGE FAMILY/ABC/1970-74. The Partridge family, a group of pop rock musicians, needed a vehicle to transport them to Ceasar's Palace in Las Vegas, so they purchased a used 1957 Chevrolet school bus from Al's Used Cars (actually purchased from Orange County School District). The family painted the bus themselves using a geometric style of the Dutch painter, Piet Mondrian (a la the Who's Magic Bus or the psychedelic bus driven by Ken Kesey and his Merry Pranksters). The rear of the bus displayed both the license plate NLX-590 and the sign "Careful, Nervous Mother Driving." After the series ended, the bus was sold over and over again until ultimately it was found abandoned in a parking lot at Lucy's Tacos in East Los Angeles. It was junked in 1987. When David Cassidy, who played Keith Partridge on the original series, went on a revival tour in 1993, he traveled in a look-alike bus. Another copy of the original bus can be seen at Universal Studios in Florida.
