White 1990 NCSHP SSP?

[tobiasfox87]

I recently picked up a 1990 NCSHP SSP, but I find it odd that it is a white car, and can't find any place where there was any type of equipment on the car, the DSO is 22 with a paint code of YO, also red interior with an auto. I was wondering if YO was common or not, since I can't seem to find any information on them. Only color I've seen them in is Black.
