Hey Cam,
Firstly congrats on the wedding mate (I got married in september, was by far the best day of my life....so far!)
I too, was also on the look out for some GT-Rs for the groomsmen (the bride/bridesmaids had commodores ), and luckily 2 members on here came through for me (one R34 GT-R, one R33 GT-R)
Hopefully you'll have the same luck. Being in newcastle, not sure whether that'll increase or decrease your chances but all the best! I think i went through about 5 or 6 possible GT-Rs when i was searching, and because situations kept changing, the lineup kept changing (but that's another story)
I cannot fault the members on here...and now i think i'm rambling..
so good luck!
