Why is there not a category for Oldsmobile in the car makes categories.?

I have questions and tips for other veiwers about my 1999 Oldsmobile Alero and Oldsmobile is not one of the car makes. Im not going to select the other makes option. That would take for ever to find any info about Oldsmobile?|||been discontinued for too many years to make it viable/no daewoo either|||Come to think of it, they don't have sections for Plymouth, Studebaker, or Nash either.
