Thanks, Bouts. The 530 you are referring to was obviously the later non-lightweight version, but nonetheless a lovely car. They had the standard M30 straight six (unmodified) and a four speed box. They were available in a "Luxury" version and a "Motor Sport" version. The Motor Sport version was only available in silver with blacked out chrome (shadowline effect), and the Scheel seats were black with the Motor Sport stripes on them. They never had any stripes, so your friend must have added them. These cars are also very rare today, and the Motor Sport version was a real stunner.
