having read this and kinda being in the same boat here is what I can tell you from my experience.
From all my research the NA imports that you are looking at are slow (there is a reason that people mostly bought turbo versions). If you want to get a good car look at one where turbo's / superchargers werent an option. MX-5 is a perfect example, its light and quick, I have a mate with one and in the right colour with the hard top it looks fantastic. Plus who cares what others think about it being girly. another example of a good RWD you might want to look at that people call girly is the new MR2s.
I would suggest a V35, It what I will get once i have saved up enough and put a deposit on a house. just remember that as a P plater in Vic you can only get a sedan V35 the 350GT is on the prohibited list.
At the moment I am driving a "boring" VS commodore and while i dont go hooning or compete in the traffic light grand prix it is more than quick enough off the mark for me and has the power to let me over take on a freeway and undertake a tram.
To add to that I am sure I would have written of an import if i got one straight away. at least if i have an accident in the VS I dont care. I know this coz when I was on my Ls I scraped it on a pillar and wasnt to worried.
any way just my 2 bobs worth.
