Forget the Z at your age and current level of income, even at $500/week. Get a Mazda BJ 323 SP2 (2L) or Laser KQ SR either 1.8L or 2L and enjoy it every day. I have a ZTT, a Subaru XV and a KQ Laser SR and guess which car is my daily and most fun to drive.... it's the trusty KQ Laser SR, it's part sports car and part shopping trolley and it never breaks down, ever!!! The Mazda BJ is better for parts though in case you crash it and have to fix it. Lots of them around. Another great hatch is the Nissan Pulsar N15 SSS. My daughter has one and OMG it's so much fun and heaps of power from the SR20. Great little car. The Mazda/Laser is better designed IMO.
