$350 really I dont think so.
I donot have a photo of the 73 Csl I had but here is one in white mine was Silver with out the wing.

I think they are the best looking production car ever built.
I paid $9500 for it in 1985 from a doctor here in Newport( he also had a M1) and sold it in 1989 for $22.5k
This what I am talking about resale value.
