The Buick Sport Wagon was a mid-size station wagon built by Buick and was shared with the Oldsmobile Vista Cruiser, Pontiac Tempest Safari and Chevrolet Chevelle Greenbrier. Featuring a raised roof and skylights over the cargo and second seat area, this model was an extended wheelbase version of the Buick Skylark station wagon. Buick Sport Wagons were built in three generations, spanning 1964–67, 1968–69, and 1970–72. During this time period, this was the only luxury level station wagon offered under the Buick model line until 1970 when the Buick Estate Wagon was returned as a full-size station wagon. 1964–1967 Series 4200/4300 (1964) Series 44200/44400 (1965-67) An innovative model was introduced on February 4, 1964. Using the new GM A platform (RWD) the Sport Wagon used a wheelbase, that was longer than the other Skylark four-door sedans and coupes. The 1964 to 1967 Sport Wagons had a standard skyroof that consisted of four tinted glass panels surrounding the elevated section of the roof over the cargo area that was earlier introduced in 1954 on the GMC Scenicruiser Bus. The traditional three VentiPorts remained denoting its junior Buick model status. The Buick V6 was standard with a three speed manual transmission, or the optional two speed Super Turbine 300 automatic. The Buick V8 was optional. A forward-facing third row of seats was optional. Sport Wagons were available in standard and more upscale "Custom" trim package and beginning in 1966 it revived the long-standing tradition offering the Woodgrain using DI-NOC a vinyl wood-grained wrap appearance. The listed retail price for the nine-passenger Sport Wagon with Custom trim package was US$3,286 ($ in dollars ). 1968–1969 Series 43400/44400 A body redesign for all 1968 Buicks featured an updated "Sweepspear" side sculpturing that showed influences from the restyled Riviera, while the wagon's roof replaced the previously-used split main skylight with a one-piece skylight over the second-row seat, which carried over to 1969. The lengthwise skylights along the cargo area remained the same and the simulated woodgrain paneling was offered optionally. The SportWagon was offered as the Skylark Series 43400 and the Skylark Custom Series 44400 included the woodgrain appearance, and was applied below the "Sweepspear" character line for 1968 and above for 1969. The 1968–69 Sport Wagon models rode on a wheelbase. This allowed for optional third row seats that was not available on the smaller wheelbase Special and DeLuxe wagons. In 1969, the "Dual-Action"
