This station wagon had something that no other non-GM station wagons offered at the time: a moonroof over the second row of seats. For the first several years of production, until 1968, the Vista Cruiser had split moonroofs over the front and second row seats. Only the Buick Sport Wagon had a similar feature.
Those most of these station wagons were sold as 4 door cars, there was a 5 door option with the Dual Action tailgate from 1969 to 1972.
The first generation of the Vista Cruiser, which lasted from 1964 to 1967, featured a 330 cubic inch Rocket V8 engine. It was the largest station wagon sold by Oldsmobile at the time. A manual transmission with a Hurst shifter was an option, as was the two speed Jetaway automatic. Three speed manual was the standard feature.
Second generation Vista Cruisers got a Turbo Hydromatic transmission option, along with a 350 or 400 cubic inch Rocket V8 engine. A 455 was offered in the final years. The 1969 Vista Cruiser was the type of car used by Eric Forman and his parents on That 70's Show. This was also the car owned by the Griswald family in National Lampoon's Vacation. It was crushed at the very beginning of that movie, to be replaced by a fictional station wagon that was uglier than sin.
A pop up sunroof was featured on third generaion Vista Cruisers. These were sold from 1974 to 1977.
The Oldsmobile Vista Cruiser has become a bit of a pop icon of the station wagon era. These cars are becoming popular with collectors who remember riding in them as kids. If you would like to buy one, I suggest you ask around at your local car shows, or better yet just check the listings on eBay. You can also find some cheap parts on there.
