As other have said, I say keep it.
At this age and value of car, knowing some fundamentals are fine is worth it - especially as you hint it's not an ideal time for you to change. If you do, you're nearly always then on the back foot, and compromised in what you can get.
Depending on how handy you are, turbo could be a fairly easy job, DIY. There may even be a kit for doing it (bearings). Otherwise, they seem to be available on an exchange basis (for replacing the whole thing).
Brakes tend to be fairly easy, too, not too pricey.
Least you haven't got one of those fancy, schmancy newer cars, where you need a gadget to tell the computer to retract the calipers, then calibrate them, after you've changed something.
