I never really realized that the pre '95 and the post '95 series were different , i thought there was just slight aesthetic differences ... but regarding to what i can read here it seems that there's also technical differences : what are they ???
At the risk of upsetting someone...try here: www.aroc155register.com you might find it tell the story to save everyone writing it all out again
ok i'm goin' to look at your link, thank you ! ... you have to know i'm use to post on a french alfa romeo forum and people there are not really aware about the 155 ... always look curious to me but the 155 is not really beloved in france because it's a front wheel drive ... so people only (or nearly) talk about the gtv6 and the 75 ... by the way it's hard to find convenient information about the 155 .
