Decent Deal? Anything stick out that should cause me to not make the trek?

The stereo was likely done by someone other than the painter. The screw hose clamps don't degrade the car or the quality of mechanical work. Just means they were not going for an original resto.
Right- it wasn't my intention to degrade those points, just to say that it wasn't the work of a big dollar resto shop, as some were alluding to. The functionality is there, just not the "correctness" that one would expect in a car in the upper 20s. At that price point it should be bordering on something special.
