99 Jimmy is it worth fixing?

I've owned this vehicle for around 5 years. It now has 150,000 miles. I just got done changing the oil and I noticed trans fluid all underneath. Not only that, but it has been leaking oil from the intake gasket (about a quart between oil change). Both front wheel bearings are shot, the expensive abs ones. There are countless minor repairs that I need to do and there is costly body damage to the right front(just physical). My question is should I keep this thing or buy a new car? I can't really afford either but what would be cheaper in the long run?
