Jarrad,
Honestly, just have a look around. I know it's biased, but all the people telling you to get a Commodore are just bogans, and down in the Illawarra, we're rife with them. I copped a fair bit of shit when I bought my R33, but then I realised that it's not my fault that their IQ is stuck by default to room temperature, so I'll just have to ignore them.
I still get P-Platers in VR commodores trying to run me; just easier to ignore and go about my business.
I've had my R33 for almost 4 years now, and while it's been a love/hate relationship (I'm hating that I'm gonna have to rip the engine out soon), all in all, the only thing I wish I'd bought other than this is a 34, although never would have found one in the colour I want
tl;dr: get what YOU wanna get, f**k everyone else. Most issues with Skylines are pretty easy-ish to fix, and if you end up getting one, happy to help out where I can.
