My brother was dating someone with an E30 (I think) convertible shed had since new. Straight six.This from an Alfa owner.
I have had BMW's and Alfa's (both pre 2004) and BMW shits all over Alfa from any perspective. After 2004 both marques share disaster status.
Had 200K kms on it and I think had had maybe 3 oil changes. He took off the rocker cover and you could hardly tell if it was a single or twin cam - sludge city.
Still ran pretty well though! I’d call that a tough engine
