As you can see there are quite some codes which I could not decode. Can anybody help me out with the missing codes?

Another question: my Bonnie was obviously built for Europe, but in which countries did Pontiac back in 89 officially sell the Bonneville?[/b]

eckoman, you have the most desireable F41 suspension

What is so desireable about this F41 option? Is it rare?

Umm - cool. Actually it felt pretty good @110mph

It was the handling setup... I wish I had it...

I got bored and decided to check my RPO. The ones with the "***" were found elsewhere, perhaps they could be added to the list on the site.

There was only one really strange thing. It says my car had the cassette and CD player? When I got it, it just had the AM/FM cassette deck. So, looking at the codes is there anything special about my Bonne?
