Gentlemen;

I'm doing some repair work to the interior and need to paint some parts. I've searched the web and found my 97 park avenue has medium grey interior. Just wondering if this was the stock color according to GM because i see they have a "medium grey" listed as an interior color for this year. Thanks

Northstar...the 1997 RPO code 171 from the service manual is listed as "Interior Trim Medium Gray." Don't know if it will match this year's medium gray though. The color family is #97.

Thanks Bigsky;

Thats what i come up with. I'm repairing/re-dyeing the leather seats. It doesn't have to be an exact match but it does look like the right code/color according to the color charts.

For seats, there are a couple options:

RPO 17D: Trim Combination Cloth, Medium Gray (97) (D)

RPO 172: Trim Combination Leather, Medium Gray (2) (97)

RPO 173: Trim Combination Leather, Medium Gray (3) (97)

Maybe there were two different shades of Medium Gray??

For interior:
RPO 171: Interior Trim Medium Gray (I) (97)
