My advice is to not listen to your friend because he doesn't know what he's talking about. Nor do some people in this thread so far.
The V-Spec's have a few cosmetic upgrades which make the cars look far better (front lip, rear carbon diffuser), it also has active LSD and an upgraded 4WD computer. There are some other minor differences such as intake and exhaust temp readings on the MFD but not much.
ALL 34 GTR's have brembos. V-Spec's may have slightly firmer suspension but there's barely a difference there.
V-Spec II's have a factory fitted carbon fibre bonnet, firmer suspension again, slightly larger rear rotors and all the V-Spec upgrades.
My advice is to:
- Buy the latest model V-Spec or V-Spec II you can afford, avoid the standard GTRs
- Avoid cars with GPS as it adds useless dashboard item which will never be able to be used in Australia
- If you're buying locally, look out for lots of rust on the underbody
- Avoid cars with aftermarket dash clusters
