Engine Damage: Part Out or Repair?

[sleepydsm]

Cylinder number one has ZERO compression, while the rest of the cylinders were at about 145. After I put the car for sale, it decided to start smoking in between shifts (blue/grey burning oil smoke). Over the last two weeks, it became progressively worse, and began to consume more and more oil. Oil and smoke would come right out of my crankcase breather filter... Plug in cylinder number one was covered in oil. I'm pretty sure the rings are shot. Should I part the car, or should I rebuild it? I'd still intend to sell the car if I rebuilt the motor. (I'm hopefully buying another 1g in a few days here haha). Essentially, it'd be easier to sell a running car than a bunch of parts and a shell....

Thanks for your suggestions!
