New brakes, fluids. Power steering, ready for conversion.
I'd have to say that's one Damn Fine, and very, very, straight looking MC5C.
Pretty typical of the occasional Unicorns that pop up out of various Gov't agencies. They can sometimes turn up with insanely low mileages and very little apparent wear and tear. Most often the agencies are required to maintain them to manufacturers specs and money is no object so any repairs and regular service intervals are maintained and they end up being preserved as if in amber. This most definitely has that look and feel about it. As long as the prolonged ocean exposure in FL hasn't done a number in it's slow insidious ways to the underlying aluminum structures that could be an extremely good vehicle to base a conversion on.
The 6V-71 in this is most likely a naturally aspirated and non-turbo'd version. For that year vintage that was the most common set up. It should be possible to easily improve the performance if a new owner wants to by various upgrades to the existing injectors and timing tricks, or you could simply look around for an already turbo'd 6V-71 and drop it in. Mind the extra heat load and the radiators will need to be improved to handle the load. The Allision will be adding it's own heat to the system, unless it's been plumbed with it's own cooling radiator. All in all it will most likely be a very nice performing coach as is and won't really need to be tinkered with, unless of course the new owner just can't resist. Good Luck to all involved in this find. Keep us informed and get yourself to the BCM site for real expert inputs from other MC5 owners and other Coach owners. They know their stuff regarding coaches.
