ummmm.... sure... and your trying to give advice?
rather than recomending a car to you, im going to sugest a few things you ned to consider, owning a car isn't just buying it:
1) insurance!! a turbo at 17 is going to cost ALOT to insure it, their may be about 2 companies (just cars and youg and cool) that'll insure you, if your keen on getting a turbo, get quotes from them before you buy anything!!
2) the cost and dificulty to maintain, jap import turbo parts cost $$$$$... if something you cant predict goes wrong with the car, it'll cost you much more than you might think to get it back up and running. also the engine bays can be harder to work on just because there is more stuff cramed into them
3) the cost of petrol!!! big power cost much more in petrol (something you may be overlooking)
just remember that while your first car is something that you'll always remember and cherish it doesnt need to be your dream car, the fact of the matter is its something for you to learn in, learn about driving, learn about maintinance, learn about parking, learn about acidents, learn about avoiding acidents, learn how to drive a manual (without destrying a gear box)... its NOT about showing off to your friends, nor is it about trying to break road rules...
Not sure if your first post has been edited, but you never mentioned anything about wanting a turo in it, which is sensible, from there on out just choose an NA version of the car you like the look of the most... there will be minimal differeance in secondary costs between the various types of a jap imports, only way you can reduce those is to get a aus delivered car
hope this helps
