HELP ME PLEEZ

[keith arthur <arthur_k@hornet.lynchburg.edu>]

Here is my story.
I bought a 1989 Audi 80 non-quattro about 6 months ago.  It had been
drive well, but burnt a good amount of oil, and I like the way it
drove.  Tehen I was going on a trip to the mountains and when the gas
pedel got at a certain spot it would make a grinding noise.  It
continued to get worse and worse and the car started to not want to go. 
The mechanic said that all othe diff fluid had leaked out and the
differencial bearings were messed up.  A rebuild tansmission is very
expensive.  The heater core also needs to be replaced, it needs new
paint and the engine will need to be rebuilt.  The interior of the car
is very nice and everything else seems to be in good condition. The car
has 140K miles

What do yall think I should do get everything fixed or start looking for
a new Audi?
Thanks in advance
Keith
