90 vs 100 maintaince/repair costs

[Scott 20191668 Bermes <scottb2460@earthlink.net>]

Hi gang,

I was hoping somebody has expereince with the $$ difference in
maintaining  an 92-94 90 vs 92-94 100 series.  I am looking around this
area and metro Atlanta and have seen, for example, a 92 100S and 93 90
CS both asking $10,500.  I am aware of the difference in size and some
bells and whistles between the two, but didn't know if the 100 had more
expensive parts which would make owning one more expensive than the
other, all things being equal in previous maintaince of the car. 
Appreciate any feedback.
