I would like to start out by saying hey, Iam kinda new around here just started posting. I was lookin gon ebay a couple of weeks ago and found a really nice 850I 6 speed. I didnt get it but it got me looking for as much info on them as I can find. I see theres alot of differnt models I, CI, CSI? not sure of the other ones. What are some of the difference in these cars? I see the later ones have more hp but other than that? I have always owned american (please dont start, Iam from MI and thats what we make here.) I remember seeing one of these on the cover of MT in 90 when they first came out and wanting one then, but being in the service and haveing a family and makeing less than 10k yr, there was no way. Now that I have a little more $ I would like to get one. What are some of the things I should look out for when buying one? Thanks.
