That doesn't sound like $3000 in repairs. The rack can be replaced for ~$200 or less. That will take care of some of the leaks as well as the inner tie rods. The front hubs can be replaced for ~$220 with good quality Moogs. You'll have $100 into a trans pan drop and fill to replace the gasket and filter. Oil leaks can usually be fixed for next to nothing.
If you do the repairs yourself you'll have a day or two into it and have less than $600 in repairs. If the car is really that bad then it may just be time to let the car go.
