I agree with your list, but I'd add cars driven in famous races like Le Mans or Mille Miglia to the top (if they place well or win then it's really serious dollars). It doesn't help 914 is one of the least loved porsche models, especially the 4 cylinder ones. 914/6 are slightly sought after, but base 914/4 like this one are just not desirable. The right buyer who loves astronomy, grew up watching Cosmos, and already has a decent classic car collection might want to add this, but I doubt they will pay much of a premium.
