If you are looking for a dirt cheap 7 passenger vehicle, the market seems to consist primarily of 60/70s American plus sized wagons or late model minivans with 300k miles on the odometer. Neither of those vehicles provide particularly good fuel economy so you are obliged to wait until Tesla P85 with rear jump seats has depreciated...or are you? What if you could get a small 7-passenger car with great fuel economy and eat your funnel cake too? Mmmm, I love funnel cake. Find this 1987 Nissan Stanza Wagon offered for $1,500 in Boise, ID via craigslist. Tip from FuelTruck.
The Nissan Prairie was sold in the USA as the Stanza Wagon and in Canada as the Multi, but it pure Nissan Sunny on the greasy side with powertrain from the Stanza/Violet. The Stanza Wagon featured a strange b-pillarless design with front door that latched at the top and bottom, and a rear sliding door complete with roll down window.
This is the picture you want to see -- it looks like some bizarro world compact minivan, or something the French would have built and called Le Box. However, the combination of wide side opening, folding rear seats, and huge rear hatch opening makes the Prairie extremely versatile for hauling all manner of oddly sized/shaped cargo. Power comes from a 2.0 liter Nissan CA-series inline-4 pushing out 102 horsepower into a 5-speed gearbox.
