It is a 1 tag 3 line car. The top line (actually the 4th line) says only EN1. Maybe it was not originally an a/c car, or a pw car for that matter. I assume those things can be added. Maybe the dash vents were installed to look factory. That cant be too hard. What I like about it is the bottom line: E63 D32 BP23 NOB. Which makes it one of only about 720 GC with the 383 4bbl, and from what I understand many of them are no longer around in anywhere near their original form. Other codes are EK2 (vit C), PRX9 (Premium Trim/leather setas/black), 000, V1X (black vinyl top), M21, M31, R11 and V5X. I have decoded the car, and it still looks mostly like a GC... still wears its badges, and a nom "built" 383 4 bbl which supposedly puts out about 500hp. The vin matches on the door tag, and of course the car title which I saw. Did not check the radiator support of the cowl? Is that a stamp up near the cabin air intakes below the trailing edge of the hood? I think I saw a picture of one on Ebay somewhere but couldnt tell exactly where. Also dont know exactly where I would find it on the rad support, and if I knew where its probably several times painted over, so I'd need to know exactly where before I go sanding on someone else nice car. Thanks.
