In the 1960's GM was trying to get the freight cost down on Vegas to keep them a budget friendly car.

At the time, a new Vega had a price tag around $2,000. Engineers from GM and Southern Pacific Railroad came up with the Vert-A-Pac. This allowed 30 cars to be shipped per boxcar instead of 18. Lowering freight costs by up to 40%.

GM engineers also designed specific oil baffles to keep oil from spilling along with specially designed carburetors, batteries and added plastic spacers between the powertrain and the chassis to prevent damage.
