I have a question about my rpo codes, I am working on working out the ones that don't show up in the decoder database, but i am wondering about code 1ay, instead of the decoder telling me it was not in the database, it gave me question marks, what is this code for? also, I am going to be tearing apart my interior soon and will be looking for my build sheet, I think maybe a little while back I came across it, but ignored and can't remember where I saw it. I would like to make a copy of it so I have some more facts on my car, where should I look for this thing?

The car is a dealer stock speical order (1AY) rather than regular stock or a customer special order (1AZ)

 

1AY= built for a dealer's stock, 1AZ= is a customer order out. Chris

 

so it's the dealer who ordered that damned red interior and didn't spend the money for the z option....damn them
