Well it seems you can never get one definite answer from people on here lol. Personally, I always say DON'T go the shitter. Buy the Skyline when you can, I got mine when I was 15 (turned 16 the next month when I got my license also) , I've owned it for 2.5 years now (I'm 18) and I don't see myself selling it anytime soon.
It was an NA and has plenty of power, but also the looks. I've done 3 drift track days in it and it is the best fun. Get into motorsport the right way, you won't regret it.
The cops won't hassle you on the road if your car isn't outrageously modified, and you act sensible. I haven't been pulled over yet!
Don't import the car, exchange rates are dead at the moment! Just use the available sources such as the classifieds section on this website, carsales, autotrader (tradingpost), ebay, your local paper occasionaly.
