I am to assume your on your p's?.
If so you have two options.
Buy a shitter, wait till your off you pee's then get a turbo skyline.
Buy a NA skyline, it will hold its value due to the crazy demand for NA imports atm, then buy a turbo something.
If your not good at saving money buy the NA liner, that way you can be cool and keep your money invested till your off your p's.
