Greyhound with Layered Roof

As far as the MC5C is concerned, so far as I know, the only Cs in Greyhound service were a group of about 200 purchased about 1979 specially designed for service in Saudi Arabia. Greyhound had entered a contract with a company called Aramco to provide service to Arabian oilfields. These bore the regular pepsi livery of the day. But an unusual characteristic of them was a double roof. Pictures I have seen of them show them as looking rather bloated with the oversize roof. This special roof design was to help cool the interior in the horrible desert heat. According to one of my books on the Hound, once the Aramco contract ended, many of the Cs returned to the U.S. and were sold to various carriers. They were popular with some airport transportation providers and somewhere, I have seen a picture of one with United Airlines titles and logo. None served with Greyhound in the U.S. that I am aware of. Recently there was one on ebay for sale in Memphis Tn. Hope this helps you, Skip Malone
