I was looking at 200SX's but they dont have quite the same appeal as an R34. Finding one with lowish miles on it that has been owned by someone who would appear to be more of an enthusiast isn't that easy either. I did also take a look at S15's but you're looking at about £8k - £10k for a standard one. Not sure it was a Silvia I was looking at, I think it was the S15a model that I liked the look of.
I know how much of a money pit tuning is, I've always dabbled with all of my bikes and my current car. That is why I am after one that has been modified tastefully already so save me taking that hit. Could be my downfall though as the engine could go pop on me but I'll be giving Abbey Motorsport a call before making a deal to see what they think of the car.
As for the other cars:
RX-8, seems a little bit bland to me, not special enough, no turbo what is tax on these?
Integra DC5, Love them and have driven one of these. Very cammy but an amazing N/A engine. Lacking serious grunt however and no turbo
S2000, Not driven, have heard insurance is really bad on these too. Like the looks, again great engine but it is still N/A. Again maybe lacking the grunt I'm after
Elise, only just about have budget for an S2 I think. If I was after a track car then one of these would be higher on the list. Not sure it suits what I'm after at the mo.
350Z, Like these too. Seem to be a lot of car for the money as well. Have two friends who each own one of these. Not turbo but it does have grunt.
Not keen on the Soarer, not to be horrible but isnt that just a wafty type barge with a Supra engine in it? I'm sure it goes well and is reliable too as I know the Supra engine is a tough nut but it just doesn't do it for me.
My current car is very cammy due to the modifications I have made to it. I've had a good dose of a cammy N/A engine for the past 5 years hence the reason I'm after something with a little more grunt / oomph. That plus the fact I'm 33 and in 3 years time I may well be up and leaving the UK and if that happens owning something like this will not happen for many many years if ever at all.
I agree I wouldnt buy clothes without trying them on, except pants and socks of course

Whilst I havent driven many cars based on experiences from my bike days there is enough information out there to gauge roughly what a car / bike will handle / perform like. After that it comes down to whether the car appeals to me, what its major faults are, how reliable is it, running costs etc etc.
