The last picture from me for this model. I let other people make their own renders, far better than mines. I prefer modeling than spending hours to have a good render. I spend never more than half an hour for an image! Maintenance on the Scenicruiser was a constant headache – partly because of the complicated nature of some of the new systems , partly because some of the components were too new and unimproved (using new, unproved, and unimproved technology), partly because the diagnostic tools and techniques were inadequate, partly because the training and availability of mechanics (and maintenance supervisors and managers) for the new model were less than optimum, partly because the technical support and repair-parts support were less than optimum, and largely because of a combination of several of those factors – along with a few other explanations – including, sadly, occasional incidents of careless or intentional abuse of the new coaches by disgusted drivers or mechanics, Super Scenicruiser In 1961 Marmon-Herrington rebuilt most Scenicruisers, a few having already been damaged in accidents. One major change was installing the newly-available Detroit Diesel 8V71 engine and a 4-speed transmission in place of the twin 4-71 engines and 3-speed transmission with 2-speed differential. Another change was adding side reinforcement plates above the rear wheels and below the windows. After the rebuilding a Super Scenicruiser badge replaced the Scenicruiser badge. The cracking problems continued, however, and many Scenicruisers that made it into the 1970s had trim panels between upper side windows removed and further reinforcements added. Greyhound and GMC did not arrive at these repairs amicably, and in 1958, Greyhound purchased the remaining stock of Motor Coach Industries. Greyhound ordered thousands of buses from MCI and thus significantly reduced orders from GMC, although Greyhound continued to buy GMC buses in small numbers for nearly another decade as Greyhound's demand exceeded MCI's manufacturing capacity. GMCs intercity bus sales slumped, and in 1980 they exited the intercity bus market.
