Saw this Wagon on Gumtree or Ebay or R31 Club??? Not sure which.
SkyWagons are the Schnitzel !!!
R34 interior sounds interesting. (I put a 34 steering wheel in mine)
Rear suspension is different to the sedans / coupes (separate shocks and springs setup) so fitting Coilovers will require some mad Fabrications.
I just chucked some low King Springs and new shocks in and some cheap second hand Rims.
(many other small things done too like bushes etc...) It's an ongoing mission.
Enjoy it. IT being the money pit.
and yes... the number plate makes no sense.
