Hi, new to subaru as I’m a Mitsubishi guy sorry however I have a thing for the old gt legacy sedan. Problem is I’m finding to many conversions that possible aren’t a gt more a vz. Currently looking at a 1989 but it shows signs of a vz even though it’s VIN in nz states it’s a GT Can anyone help me with the expert eye in ways to identify exact model most have been altered so it’s hard as I’m not a full enthusiast yet cheers
