Rounding out this week's Big Three Vintage Vans series is a 1964 Chevy Corvair Greenbrier Sportswagon. Perhaps the most homely, and also the most unconventional, the Greenbrier was a Corvan 95 cargo van with side windows and passenger seats. Introduced in 1961, it beat the Dodge A100 to market and came out at the same time as the Ford Econoline. It was direct competition to the existing Volkswagen Microbus as well. And, like the VW, the Greenbrier was no powerhouse. Equipped with a flat-six, the Corvair produced 80 horsepower to motivate that heavy-looking body along. Considering that the Microbus used a flat-four making only 51 hp at the time, the Corvair was something of an improvement. Still, a decent straight-six '64 Econoline would probably blow its doors off.
