Hey, it was on the shelf after all. The magazine is from Oct-Nov '85, cost a mere $2.80 (those were the days eh?) and has a Mad Max interceptor on the cover. The RS2000 is more of a mid-blue colour, with NSW license plate "RISKY".
Flipping through the magazine is a bit of a trip. For those who weren't around then, it was a time when chrome wheels with gold centers were hot stuff , and several cars in this issue have that look, including a Holden with 24k plated Cragars, and the aforementioned RS2000. Peter Brock spruiked for HM headers and Scorcher ignitions, Goodyear NCT tires were so great they got a 2 page spread proclaiming you'd effectively get a whole new car by fitting them, Alpine had incredible deals on stereos (incredibly expensive by today's standards anyway), you could view the latest Globe wheels and those pop-up perspex sun rooves that were so popular at the time (the coolest having separate panels for driver and passenger). A little female nudity was still possible in advertising back then too. Ahhh, nostalgia.
Anyway, if this is the car, PM me your email address, and I'll get a decent scan of the article to you sometime soon.
