Yup a model specific site will get you more members / interaction with model in common and quite a few of the members on here contribute to other model specific sites - with this forum we throw a wide Subaru net but it takes time to build the depth with some areas being more successful than others.
There is a GT86 parked up that we pass quite regularly by me and I get a nudge in the ribs from SWMBO as she fancies a little two door number so I can see one of those being added to the list at some point
