I think mine is some sort of weird Frankenstein Job One. It must have been one of the very early ones. I have some Job One features and some Job Two features. For example, my odometer is white numbers on black, which, according to that link, is a Job Two feature.
Also, I have the 6-disc CD changer but no factory subwoofer. There are some other peculiarities, too. Oh well, no biggee...94K miles, no major problems, still running strong, can't complain!
