Back around 1992, I bought a 1980 Dodge Aspen wagon for 50 bucks that had a brand new state inspection sticker and a bad miss. Planning to get a year out of it, I gave it a quick tune up. The miss stayed. Compression test revealed almost zero on number six. Decided to just drive it. I never actually measured the zero to sixty times, mainly because I didn't have a sundial or calendar in the car with me. It pushed oil out the exhaust to the point where it would actually leave a golf ball sized spot on the ground under the tailpipe. Gave up buying oil for it, and just carried a 5 gallon jug of used oil with me everywhere. Drive until the valvetrain grew excessively noisy, pull off the road, grab my jug, "glug glug glug, yeah that's probably 4 quarts", slam the hood and go some more. It survived 9 months of this, before the dreaded knock began one subzero night. The autopsy revealed that the entire crown of number six piston was fragments in the oil pan. Not sure how or why, because it was already that way at purchase.
