Was the stereo (and antenna) factory installed or dealer installed? Was that side trim dealer installed?
there were plenty of 75 1.8's and I have never personally seen a 914 that didn't have at least one wire hanging down below the dash
That is probably the 2nd cleanest, 2nd most original 914 I've ever seen but it still is only worth about $10k tops IMO.
(the cleanest 914 I've seen belongs to a guy who lives about 3 blocks away from me, I've only seen his car one time and that was at Dunkel's. It was a white 2 liter IIRC.)
