RPO code help
So, if the VIN number of the car in question comes back with RPO 192 (Ebony leather) but it has no leather seats, then someone has changed the seats or the VIN you have searched is not the car's actual VIN (or the database at compnine is wrong - you could double check with a GM dealer at the parts counter.) If the seats are cloth, but still Ebony in color, then they were originally out of a car with an RPO of 19B.
NP5 is a leather wrapped steering wheel, but UK3 would be a leather wrapped steering wheel w/radio controls on a 2000+ car (both RPOs should appear if wheel is leather and has radio controls.) There is no color specified for this as it was only available in one color for a given model year (same as the dash) - regardless of interior trim or seat color.
N73 should be the silver painted SS wheels (I think this same code was used for both the earlier C4 ZR1-style and also the later 10-spoke version.) So then this car, or at least the VIN you're searching, should be an SS originally (RPO WU8.) And with Ebony interior color codes, it would have to be a 2000-02 model and therefore have the 10-spoke SS wheels if they are still original ('99 was the last year for silver painted C4 ZR1-style.)

As far as the wheels I figured out it has the 35th anniversary SS wheels on it. That's really what was confusing me.

Actually, '97-'99 was "Dark Gray" (Code 14, so RPOs 14I and 14B/142), while 2000-'02 was "Ebony" (Code 19.....19I and 19B/192.) There was never an actual black - Ebony was as close as it came but wasn't a real black as some people think/call it (this becomes evident when compared to actual black items, such as the power window switches and blinker stalk.) Ebony was just a really dark charcoal gray color, while "Dark Gray" (14I/B/2) was more of a medium gray sort of shade.
But there were other interior color codes as well, depending on the year, ranging from neutral (Code 52) to Red Accent (cloth only, Code 73B.)
Ultimately, if the car you're looking at has a VIN with RPOs that call for 192 seats (leather) but the car has cloth of any color, then something is wrong (either an interior swap was done, or the VIN isn't the right one, or Compnine is wrong - which, if it comes to that, you can verify at a GM dealer parts counter via their VIS.)

Compnine is definitely correct about 192 being an RPO for leather, but it's possible that they are just showing the wrong code for the VIN in question. But if you can check the original sticker and VIN, then that's all you would need to verify to be certain.
19B = cloth
192 = leather
Whichever code appears on the that sticker (SPID) is how the car originally came, regardless of what's in it now. But, again, make sure to verify the VIN on that SPID because it might not match the car (swapped door, or wrong sticker applied at the factory - that actually happened to one of mine that I bought brand new.)
Are you sure that's not a '99 manual? I ask because 99U (Hugger Orange) is present and this was a '99 only color.

Yes, this from a 2000 manual. I have it as a pdf and as actual manuals. I believe all the equipment codes should be correct, unless they was new like the ebony interior codes. I noticed the Hugger paint codes before, just figured they missed the editing changes and weren't deleted.


Since eveyone likes pics

Car in question, yep I bought it. What's strange is that he gave me a copy of the rpo codes that the dealer printed out and there was no 19I on there. I told him what I found and he said that the car has always been cloth that he knew of. Doesn't matter much I'll probably change it at some point.
Thanks for the help, that's why I love this forum. So many knowledgeable people willing to help out!
A headlight restoration would clean up the front end nicely. Too bad they get cataracts so easily.Does the dealer print-out have the proper matching VIN? How about the actual SPID sticker on the door? If there is no 19I, then it wasn't an Ebony interior car originally.
19I = Ebony interior trim
192 = Ebony Leather
19B = Ebony Cloth
If the car came with medium gray or neutral interior colors then it would be 92- or 52-, respectively.

Or does the printout and door show a different color code completely (such as 92B or 73B)?
The F-body leather is rather poor quality, so the cloth may have been swapped in to replace prematurely worn seats at some point. Or, if the seats were still nice, someone who owned the car in the past may have swapped interiors with someone else to make a little extra cash prior to selling the car. Honestly I'd rather have the cloth, it's much more durable and comfortable in temperature extremes, but I do agree that the pattern isn't visually appealing on the 2000-'02 style. However that's all just a matter of personal preference.
In any event, at least you now know for sure how the car came originally.
