The light weight compared to the room and size, the fact that any GM V8 is pretty much a bolt in, handling is excellent for very little expense. A handful have some value, but they were mass produced family cars, by and large, so with exception of GNX, GN, H.O., 442, SS and the ‘80 Grand Am, there isn’t much pizzazz. The ‘80 Grand Prix SJ had some good pieces but the pre’81 style was dull.
