66 chevelle ss

[redcars427]

A friend of my son's grandfather died recently and the family wants to sell his 66 chevelle ss. My son was looking at it for me and sent some pictures. The car has been stored in his barn for 30 years. It is a one owner 360 hp with the original engine and four speed. The trim tag is a 66138 with the color being LL {med blue?) with a blue interior. The car has 51,000 miles. I thought I knew these cars from the old days but a couple things are not the way my memory remembers these cars. First it has a bench seat. I thought they came only with bucket seats. Second the engine has a holley carb on an iron manifold. Third the back panel between the rear lights is body color. I thought it would be black. Glass is good. Interior needs work. Body is decent.Whats it worth?
