Ir is a CMX, so I think that had its own code as an option package. The white striping had a code, as did the fake convertible top. Power mirrors, both sides, like yours. Power seats, buckets in this case. Remote trunk release. The "Chronometer" digital clock. Criise control, but regular (i.e. not temperature controlled) air conditioning. Separate power amp in the trunk. I think there were two colour codes, one for the body (red), one for the vunyl top (white). Console (I think it gets its own code). AM/FM Cassette deck. Tinted glass. 318-4BBL/A999 power train. Power Windows and Locks. A couple of trim codes and lighting packages. Had the brushed aluminum look interior accent package vs. the fake featherwood accent package that was in my other Mirada and on my Cordoba. Probably doesn't look as luxurious, but it held up better to the sun.
I think the car was only missing the temperature controlled air to have every possible option available.
