Here's some more information about this wagon, courtesy of the owner:
This is a picture of a 1972 Oldsmobile Vista Cruiser 442 wagon, complete with matching surfboard! Next to it is my matching 1972 W30 convertible; one of only 33 made (yes, it has the proper x in the chassis #). These two cars have accumulated more trophies as individuals than any other cars in the Pacific Southwest Zone of the Oldsmobile Club of America, and because of the lack of rust in California, have to be considered the two nicest examples anywhere.
The W30 has never been beaten in competition and neither has the wagon. The W30 is like new with a stick shift. The wagon is one of 3 made that were not 1972 pace car track white wagons (6 of those were made). Everything is original except the $3,000 stereo system which is hidden an built in so as to not devalue the car. Both cars were part of an estate and built and ordered as a pair.
