Based on the Cyclone M.II derailleurs with top mount shift levers and Sugino GS crankest with drilled chainrings, it should be a circa 1983-1984 model, while the mono-tone paint would indicate 1983. This was a nice,f airly light lower mid-range model with a CrMo double butted main triangle and aluminum rims Original MSRP was approximately $350.

Provided it was fully overhauled and ride to ride, I would have no qualms about the price. However, there is a lot of dirt around the bottom bracket shell and the crank extractor hole is filled with dirt. This suggests the bicycle has been ridden in very dirty conditions since its last overhaul and the bearing condition is suspect. It almost certainly needs an overhaul and may need new bearings and races. This can add quite a bit to the cost, especially if you can't do the work yourself.
