Well crap! Advice needed with shot engine

[finaltable]

My Supra apparently started leaking oil. I drive 500 miles a week and didn't notice how low the oil pressure got. I took it in to have it looked at and the mechanic said I was 3 quarts low when it came in and enough damage was done that a rod is knocking so my engine is shot. (His technical description.)

I had been planning to sell it in a few months, though I had planned on driving it until then. He said that without taking the oil pan off they can't know how bad the damage is so I now have no idea how long until the engine craps out completely.

The car has 137K miles and in great shape is possibly worth 3K. While it is in good shape, the seats need to be recovered so it isn't even worth that much.

If you were in this situation, what would you do?
