Thinking of an upgrade

I WOULD rule out the Commodore immediately because its six-cylinder engine will be too thirsty for your budget. But any cars fitting your price range will almost certainly be unreliable and expensive in the long run. Even though you're stepping up in price range, $5000 will buy an old car that is only marginally better than the cheapies you've been driving. You'll be better if you can spend $10,000 on a car that's still got some life left in it. I'd recommend a five-year-old Nissan Pulsar, Ford Laser, Mitsubishi Lancer or Toyota Corolla. They will still accommodate four and will be much cheaper to run than the Magna, Camry or Commodore.
