I wondered if that would be confusing...
HHRs are cars.
GM built a version that wears a "Panel" nameplate. Many vanners have bought, customized, and brought them to runs. we allow them as the contemporary panel. If Chrysler had built the PT panel that so many of us drooled over, we would allow them, too. As it is, there is a company that converts the PTs into panels, but they are still cars. No different than if you blocked the windows out on a Hyundai or whatever and called it a panel...no deal!
There has not been a US made panel sold in the States since 1972. At that time, there were panel and window versions available and they were built on Truck chassis. We allow all of those variations, just as we allow the window versions of vans.
Back in the day there were car based panel looking vehicles, also, called sedan deliveries. They are not allowed at the Nats, although a few have slipped in under the radar as recently as the Butler Nats. All of this refers only to the Nationals, not local runs.
Generally speaking, Panels have 2 doors in the back, and sedan deliveries have one door. There are xceptions with tailgates, but I said generally!
Hope this makes more sense!
And to make it more of a mess, Willys at one time made a panel truck! And we have had at least one at a Nats (Los Banos)
