All this talk about poor engineering, difficulty in replacing items, etc makes my old MC-8 look simple. I mean, my water pump is right there in front. Sure, some things will be difficult to access... the air compressor, power steering pump, and alternator are all on the back (far side) of the engine. I can crawl in there and get to most parts, though. The radiators are simple to remove and install with a helper. Sure, I may not get the best fuel economy, but it'll take a lot of miles to make up the difference in price of the bus. Of course, an old, worn out 8V-71 can certainly be a P.I.A. As to brands, I wanted an MCI due to the fact that there are so many around - I see -8's and 96A3's around town regularly doing shuttle service. The power may be lacking, it may be only 96" wide, and it definitely doesn't look even slightly modern, but for a first time 'bus buyer', I certainly can't bitch (much) about my old tech. MC-8 and 8V-71.
