58U. The Medusa of the G-body Monte SS color palette.
Now that's two people that have claims to have seen this bigfoot of a car. I had an 86 Monte SS bought new, and I always noticed when someone else was driving a similar car. And I've never seen this color on an 87 Monte SS ever. Which doesn't mean anything. I've just never seen one. The silver was semi-rare as compared to black or white, and even burgundy, but I'd seen enough of them to know that silver was a color choice for public consumption without ever looking at a brochure. It was many years after this that I was even aware that a light brown 87 Monte SS supposedly existed. I think it would have been different had GM shown all the Monte SS colors in the brocure on the car pics themselves. Maybe. I dunno.
GM always did some stupid sh*t with their production and I wouldn't put anything past them. PERHAPS...just thinking out loud here...the color was initially offered, and then after it wasn't well-received, got dumped early on. There may be a dealer bulletin somewhere announcing that if that was the case. I've seen that before. Or crap gets added or changed mid-cycle (think 84
H/O fan belt routing and horn cap) and nobody says anything. And perhaps those early cars that had 58U didn't survive.
At any rate, you would think there would be some sort of evidence out there of "proof of life". Usually, factory information was printed up before the production run, but without a date stamp, who knows? Anyway, looking up the information, no mention of 58 as an available color on the 87 Monte SS. As such, the disclaimer on the bottom of every page says to refer to the dealer ordering information for the latest info. Basically meaning it's always "subject to change."
And looking at the dealer ordering guide as revised of 9/8/86, it still isn't showing the availability of 58.
We do have some evidence 58 was at least authorized to be available early on. One, the engineering book that
84 W40 has, and the August printing of the Monte Carlo dealership brochure. ???? They've also done the "late availability" thing on some options/colors, so it wouldn't even suprise me that it might have been a late model year offering and nobody ever took them up on it because they didn't advertise it?
Conflicting info from GM themselves. Imagine that.
