Interesting car, and in the brochure-car colors - seems to be an early RR, but it has the '69-style pleated seat inserts (instead of flat Reed grain like 3 of my originals had), and yet the silver & black was '68 only. I guess Lynch Road was ahead of the other plants? Weirder yet, my current '68 is a later (SPD 2/12/68) Lynch Rd car, and its base interior has the Reed inserts.
