Actually “barn” is a sweet word used in the title but this car looks to be stored somewhere more likely to a container than a barn.
However, the point is that this car has been stored since many years and, if the period photo provided by the seller is one of the last taken before the car was stored, it looks like this car has been forgotten since, at least, the late seventies. The car still has the same rear tires pictured in such photo and the color too has not changed since then.
The seller says that the car has a bigger than stock engine (?) and that this is a two owner car. The first thing that must be done by a potential buyer is asking for more photos, especially of undercarriage and interiors, but there are still few chances that this car could need only a mechanical fixing before hitting the road again. Find it for sale at $12,950 o.b.o. here in Seattle, WA.
