My female school bus driver had a Street Van back in the '80s. It was maroon with Keystone Classics. I think it was a '79.

I agree that rust was a big part of why they disappeared. Also, gas mileage wasn't great. SUVs and minivans didn't help, either.

Marshall Vans was a big conversion company based out of Carlisle, PA back in the day (I don't think they are related to the Marshall Vans in Cali that exists today). I used to work for a body shop that did a lot of the paint on them (I think they used multiple body shops) but that was long before I worked there. My old boss used to tell me how he would line the vans up and paint the graphics on a couple of them at the same time - using the same colors. He would even have buddies come over to help. Anything to get them out the door.

From about 1989 to 1994 I worked at the local Ford dealer that sold quite a few conversion vans. I think the builder then was Capitol Conversions. They were expensive but everything on them was so cheap.
