My brother in-law has a 70 SS454 #'s matching 4spd m22 Chevelle sitting outside. I think he may finally sell me the car. It is fairly solid still but needs welding and restoration. He still has the window sticker and the build sheet. The problem is that the car was stolen once and recovered and the cowl tag was stolen. Is this car a good investment? I can give more info later if I hear from anyone.
